Hello. I need help identifying these 3 capacitors so I can place an order. Thanks you!
Welcome to the community.
What are the dimensions “LxWxH” of each capacitor?
I used a caliper to measure.
687J - 4.31 x 7.4 x 2.77 (mm) or .17 x .29 x .11 (inch)
107A - 3.44 x 2.83 x 1.87 (mm) or .135 x .112 x .735 (inch)
226C - 2.77 x 3.35 x 1.71 (mm) or .109 x .132 x .067 (inch)
Interesting. The photos were stock photos. The actual capacitor that I have is 226C rather than 226D. Is it a huge difference? Hopefully this helps. Thank you!
Hi RatchetM,
Welcome to the TechForum.
The digits on the top line represent the capacitance value, in picofarads, which is 1/1,000,000 of a microfarad. The first two digits are the significant digits and the third is the number of zeroes following the significant digits.
So, 226 = 22,000,000pF, which is 22uF
Likewise, 687 = 680,000,000pF = 680uF
… and 107 = 100,000,000pF = 100uF
The letter codes are as follows (image taken from the Kyocera TPS series datasheet)
Typically, dimensions are listed as length, width, height, with length representing the distance from one contact to the other, as indicated in this drawing:
And this table indicates the standard case sizes and their representative letter code designations (not to be confused with the voltage letter designations):
The little delta symbol (or stylized “A”) to the left of the upper digits most likely indicates an AVX-branded product, which has since been acquired by Kyocera in 2020.
Unfortunately, it’s difficult to impossible to know which particular series of AVX/Kyocera tantalum capacitors you have, but here’s a link to possible options for each:
687J → 680uF, 6.3V Probably case size D
107A → 100uF, 10V Probably case size B
226C → 22uF, 16V Probably case B (though case B is typically about 1.9mm high)
Where an option exists, picking a higher voltage part can give you an extra level of headroom, which is desirable.
