SparkFun Capacitor Kit

This is a kit that provides you with a basic assortment of capacitors to start or continue your electronics tinkering. No more looking under your desk to see if you can find a spare capacitor you might have dropped a year ago. With this kit you get over 100 of the most popular capacitors. As a bonus they come in a box with a sticker to help you identify which capacitor is which.

This assortment of capacitors makes a great gift for beginner and advanced electronics nerds at any time of year!

    What are the tolerances of these capacitors?

      Hi there, it sounds like you are looking for technical assistance. Please use the link in the banner above, to get started with posting a topic in our forums. Our technical support team will do their best to assist you.

      Otherwise, the voltage rating is listed in the identification guide.

      • Erik van Zijst / about 5 years ago / 1

        Doesn't the manufacturer provide this along with the product? The Identification Guide does not mention tolerances.

        • santaimpersonator / about 5 years ago / 1

          The identification guide does list the voltage rating for the capacitor, which is technically a tolerance of the capacitor. However, if you reach out to our technical support team with the exact details of what you are looking for, we can try to make an inquiry with the manufacturer.

          That being said, these are cheaper replacement parts... so I expect the tolerance on the capacity to reflect that. Additionally, based on the markings, the manufacturer may not have that information.

    I wish you'd carry more ceramic caps outside of this kit!!

  • cluttmann / about 9 years ago / 1

    Are pF and nF capacitors tantalum or ceramic? I am looking for tantalum capacitors kit...

    • Sembazuru / about 9 years ago * / 1

      They make tantalums in pF and nF scales? I thought they were primarily µF scales and up as a smaller size/µF package than aluminum electrolytics? (And having lower ESR, more spectacular failure modes, etc.)

      The pF and nF scales are probably MLCC, also known by some as monolithic ceramics (that's what the pictures look like).

      Ok... I just quickly checked DigiKey and found tantalums in the tens of nF range, the cheapest were $0.31/ea and axial. The picture caps are radial. My (generally uninformed) guess is tantalums in this size are specialty components, not something one would expect in a generic kit such as this.

      • l0gikG8 / about 9 years ago * / 1

        If you are set on tantalum, then you could take your chances with a grab bag. Jameco also has a kit that goes down to 100nF. However this Sparkfun kit is a good general purpose ceramic and electrolytic kit with a nice balance between price, number of components and capacitance range.

  • steve_does_stuff / about 9 years ago / 1

    Awesome! The resistor kit has really come in handy - so much easier than trying to guess what resistors/capacitors you'll need when ordering

  • Sembazuru / about 9 years ago / 1

    I was going to ask if the sticker could be included in the box (instead of pasted to the outside of the box as shown in the new product video). This would allow the sticker to be put on the divided bin that the caps would eventually be put into for organization. But, I see you provide the sticker image as a pdf and I have a bunch of label paper sitting under my printer. Thanx.

    • M-Short / about 9 years ago / 1

      Yep, you have options. Also, each value has its own little baggy so you can just leave them all in the box for those without spare bins. I want to see someone blow it up poster size and place it on the wall!

      • Sembazuru / about 9 years ago / 1

        I don't see why even wall sized wouldn't work. I zoomed in 6400% in Adobe Reader and the only elements that looked rasterized are the white speckled weathering, and the digits for the barcode. Everything else appears to be vector (though I suppose the barcode itself could be rasterized, but it wouldn't show). Just need a ream of copy paper and time on a color printer, or a roll of paper and access to time on a large-format printer. I used to have the latter....

cap kit

I was building a qrp labs 20m kit and was missing a 104 cap, most likely on the floor hiding under a paper dot. so I ordered the cap kit. great service and fast shipping. bookmark the site.

Just what I need

The Capacitor Kit was just what I needed in capacitors. It had a variety of capacitors, ranging from 10 picofarad to 100 microfarad. The larger capacitors are very good, and seem reliable, for cutting power supply glitches, and the smaller ones in timing circuits.on the 555. They came on time, too, which i was pleased with. Ordering wasn't too difficult, after being found on the SparkFun site. Because of this, I think this is a good buy.
