SMT Manufacturing – tips & tricks: Resistor packs


SMT Manufacturing – tips & tricks: Resistor packs… For prototyping, modding, hacking and reworking, its good to have a range of resistors in your favorite package size. We like the digikey box packs of resistors, and have a set of the 5% in 0603, 0805 and 1206. Sometimes we wish there were more values so we may get the 0805 in 1% for a few values. Either way, having a resistor set is essential!

  1. I have the sets from Seeed Studios, which I’m really happy with. That said, I’ve found very similar things on eBay lately, for way, way cheaper than Digi or Mouser has them. Search for “resistor kit,” and make sure it has many, many thousands of pieces (they’re tiny). Also: I recommend 0805. It spans 0.1″ through-holes nicely, which is great when you’re short a part on a Radio Shack protoboard. 0805 is about the right size; 0603 is too small, 1206 is awkwardly large once you’re used to it (though it’s what my SMD Badge kit uses, since it’s aimed at newbie SMD solderers).

  2. Nice kits, but the 0805 I clicked on was $60. For starving students there are cheapie kits on eBay from $5-$10 shipped, and they often include a free capacitor kit. MDFLY has a nice set in clear pages for organizing in a book. The quality of these Rs isn’t great, and the kits not as complete, but for prototyping they’re super cheap and handy.

  3. One thing I’ve wondered about, is how big a convenience advantage the resistor kits from digikey are, as opposed to ordering the exact same quantities/values separately which is considerably cheaper. I guess it is fairly tedious to enter all the values separately though.

  4. Also check out Seeed Studio’s Resistor book which has 0805s but 177 different values for the same price as Digi-Key’s box.


    They also have a 0805 Cap book.

  5. You can get assortments or even full reels way cheaper on Ebay.

  6. I went the ebay route as well, and bought a few hundred of little spring-loaded configurable storage boxes to keep them in (like these http://www.dealextreme.com/p/configurable-storage-toolboxes-3-pack-4727). I got mine in Shenzhen.

    I prefer them to the binder approach — it’s very quick to fish parts out with tweezers while building things.
