Title: Finally making a parts order to stock my bench.
Post by: ThePastRecedes on July 30, 2014, 09:47:15 PM
I've been building pedals for a couple years now but I only order parts on a pedal by pedal basis.

Edit: Here is the parts order. http://www.mouser.com/ProjectManager/ProjectDetail.aspx?AccessID=f526a5afd3
There are a few values missing but this should be fine for majority of my projects. Bellow is listed what I have.

200 of each xicon resistors from mouser.
100R
330R
470R
1K
1K8
2K2
3K3
3K9
4K7
5K6
6K8
10K
22K
27K
39K
47K
56K
100K
220K
330K
390K
470K
560K
1M
2M2
10M

Panasonic Electros
470u - 10
100u - 100
10u -100
1u - 100

Panasonic Film Caps
220n – 100
100n – 100
47n – 100
33n – 100
22n – 100 
10n – 100

MLCC
4n7 – 100
3n3 – 100 
2n2 – 100 
1nf – 100

Think you've probably got the right total number of caps, but you're over/under on a lot of them.

I'd bump up the qty on the 10/47/100 to at least 300

I'd add a 100 of 1 nF

12/15/18/27/56/68/82 - it's going to take a long time to burn through 100 of those.  40 of each would probably cover you for a lifetime of pedals.

Same for 120/150/180/270/330/560/680 - 40

390 nF - you're going to build 100 Sunkings?  You're the reason the boards never in stock.

Haha  ;D You've got a point. It was mainly to hit the price breaks on mouser but I think I'd end up with way too many.

Is get values between 560k and 1m

Post by: Govmnt_Lacky on July 30, 2014, 11:11:48 PM
I would also recommend the following:

330R
470R
Might want to reconsider 10M. That's pretty big! Maybe more like 3M9?

1n5
Maybe max order for 100n as it seems to be one of the most popular.

NO Pf caps?

Where's the electros?

;D
Title: Re: Finally making a parts order to stock my bench.
Post by: Luke51411 on July 30, 2014, 11:14:41 PM
I was just going to mention electros
Definitely get 4.7u, 10u, 47u, and 100u
Probably 22 and 33 denominations as well

I'm pretty sorted for the pF caps... but how could I for get the electors  :o this is why I always have a million orders for a single project...
Title: Re: Finally making a parts order to stock my bench.
Post by: Govmnt_Lacky on July 30, 2014, 11:32:42 PM
1uF, 2.2uF, 4.7uF, 10uF, 22uF, 47uF, 100uF, 220uF, and 470uF

You can get more but, those are the "most" used  ;D

I have a confession:
I ordered stuff on a onesy-twosy basis for a long time, until it finally dawned on me that there was a better way! Plus, I finally looked at the price breaks. :D
But really, the main benefit was convenience. It's kinda nice when you can just about build a project with stock on hand.
I built up stock on stuff like the resistors over time though, as I ran into the same values. Same with caps ... plus, over time I became partial to certain brands, and then began to order common values in lots of 100. On less common values, I still tend to order at a lower price break, and it takes a little time to get familiar with some price breaks on Mouser.

I think you're on the right track, but while you're at it, might as well get some sockets too, both IC sockets, and the in line ones for transistors and components.

What I did was list out a shopping list for the first 5 pedals I wanted to make, then gauged the most useful values from that.  But now I'm about done with my first pedal and already looking for parts for 3 or 4 more... so maybe look at a shopping list for the first 10 pedals lol

Hey ThePast, check out this thread I started a while back.  Might help you plan your purchase (of film caps)

It takes some time, but when you find you need a new value for a resistor etc...just pick up 200 xicons from mouser. 

I think Tayda has the best prices on sockets.

When ordering electros, pay attention to the diameter and height. You should get 25v (16v are okay but won't work in charge pump 18v builds). Electros should be 5mm dia up to about 100uF then at 100uF it will be 6.3mm dia. 220uF will be 8mm diameter.  Try to get the shortest height ones you can, nothing over 11mm - under is better.  Mouser has great name brand electros and I trust them more than the Tayda "chong" brands.

I recently shared a Mouser shopping cart with all ECQ-v panasonic film caps from 10n to 1uF. Search for "Panasonic" and the thread should come up on the forum.  I like the panasonics best, but Epcos or Kemet are good too. It's nice when they all match on a PCB....so keep that in mind.

It's great having a nicely organized stash of components....kind of like going into your kitchen and saying "what do I want to make today". 

I feel you are doing it right. If I had to do it all over I would order 90% of my components from Mouser.  Tayda is okay but at the price break points mouser is a better deal and higher quality for about the same money.   Nichicon, Kemet, xicon, panasonic, Epcos, are all good brands.

Edit:  Chromesphere's (paul) also has lots of good deals too for quality parts.

I just did my first big mouser order about an hour ago. Doing the math on the price breaks, it made sense to go big.  Resistors are super cheap, so are diodes

Yeah, this is spot on and would have saved me some early grief.  Also, you can save some shipping money by planning several builds ahead and including the onesie-twosie things you'll need with the bigger bulk order.

There's always something I seem to miss though...  ::)

That's part of the fun, I suppose.  Another excuse to stock up on 100qty of that part you are missing....  I like Smallbear for grabbing specialized components that are hard to find.  I also find lots of good stuff on eBay especially if you buy in qty and don't mind waiting a couple weeks...LEDs, various ICs, diodes, transistors, voltage regulators, etc.  Sometimes you can snag some really hard to find stuff, or a whole boatload of common stuff for cheeep.

I really wish Tayda would get their #$*% together and stock up on more "A" and "C" taper PCB mount 16mm pots.  They are by far the best place to get 16mm "B" solid shaft PCB mount pots for around $0.55 each.  Other values, I have to get from "other suppliers" at about twice the cost.   :o   I don't mind soldering solid jumper wires to Tayda pots for my own builds, but if I am making for someone else...I want robust and professional PCB mount pots.

When I first started, I mostly used offboard wiring to the pots.  As my building progressed, I found that PCB mount pots are the cat's meow and pretty much the only way I fly now.  Not only do they eliminate some offboard wiring, they hold the board in place without you having to design a solution (tape, standoffs, etc).

Thanks for the link! I'll use it for my film caps.

Oh man I didn't even think about diodes.
I'm thinking some the following 1n4148, 1n4001, 1N914, 1N34?

That's the thread that got me thinking. I just realized the amount of shipping I've spent on the last few pedal builds wasn't worth it.

Is there any reason you went for the EQC-V other than size? I've been using the film box type from tayda since I started and I've never had problems with them.

Heres a link for the resistors for any one who is planning to the same in the future or uses the search function.

I'll post the caps once I decide on which brands/models to get.

Mostly for reliability, aesthetics, sound, and the fact I know they are great caps. Sad they are soon to be discontinued. I have a bunch of Tayda caps and they are alright. Once in a while I will find a mislabeled Tayda cap, or a double stamped label. There also seems to be no continuity between the colors on Tayda.  It's awesome seeing a build with all ECQ-V and high quality electros. I still use my Tayda caps for verifying builds and other stuff- they have their place. However if you are starting up from scratch....check the prices of Tayda vs Ecq in quantity at mouser....almost a wash. 

It stands worth mentioning that Newark runs specials on Epcos box caps for 6c or about a pretty often.

What do you guys use for ceramic?  I like the ones small bear sells, but can't find them on mouser, or something similar.  A lot of the stuff I see on here with mouser, uses the multi layer.

Post by: m-Kresol on August 14, 2014, 03:34:30 PM
Did you order yet? If so, could you share the list for caps? I'm thinking about doing the same, as this is the cheaper option over time than ordering 10-20 resistors at a time and a few caps.... I have no clue if I ever will use that many parts though...

They're pricey, but what you're looking for are MLCC that are COG temp. coefficient. I use them for anything under 1n.


Here's a link to some results (http://www.mouser.com/Passive-Components/Capacitors/MLCCs/Multilayer-Ceramic-Capacitors-MLCC-Leaded/_/N-bw5t5Zscv7?P=1yzt46s)

I haven't got round to it yet. It ended up a little out my budget so I'll have to wait for my next pay check before I order.

I'll get some BOM up soon.

I've used them in a few builds. They're pretty good. Depending on the price difference I would just go for the panasonics

It's not huge, just pricing different brands to see if there's any major differences in price.

I'd say order a few and try them out. I personally like the aesthetics o the Panasonic caps but these (IMO) work just as good.

Nichicon brand electros are very good quality and offer a wide range of short up to 50V.

Most of the electro i use are Nichicons and Panasonic, most of them are 25-35V rating and are smaller than the Kemet box cap i use.

Panasonic also offer really good caps at good pricing, you'll either end up using Nichicon or Panasonic depending of the price/size/voltage you are shopping for. The quality vs convenience vs price can't be beaten.

TDK mlcc is what i use for everything under 1nf. pricey... but tight on tolerance compared to other ceramics where it can vary widely.

If you ever need to stash on odd resistors values and Xicon don't have them in 1%, look for KOA, they have them all and the price is very good too.
