320 PCS 16 Values 20 Each 1206 SMD Capacitor Assorted Kit 10P-22UF Chip Ceramic Capacitor Electronic DIY Kit(320 PCS 16 Values 1206)

Nicely organized in order of value. The ones I have used tested within specs of the listed value. A good value.

I use them to fine adjust the digital clock slowing it down if running too fast by soldering in parallel with the quartz. I use values from 1 to 10 pF to slow it down from running 5 seconds fast per month

No problems with these caps

I bought these for the 4.7uF capacitors. I pretested before installing. 1 out of 20 was 4.6uF, the rest were 4.1 avg. I spot checked the 10uF it was 8.1uf. I checked a 5.6nF is was 4.8nF. Returned the whole lot.

I wanted cheap variety for a project that was going to involve trial and error, so I ordered two sets of these (40 each value) and tested every one of them. Labeled and Measured values (1kHz) with standard deviations were as follows: 226 (22uF): 11.2 +/- 0.4 uF 106 (10uF): 7.05 +/- 0.4 uF 475 (4.7uF): 2.99 +/- 0.4 uF 225 (2.2uF): 1.52 +/- 0.03 uF 105 (1uF): 830 +/- 39 nF 474 (470nF): 357 +/- 19 nF 104 (100nF): 175 +/- 10 nF 103 (10nF): 10.6 +/- 2.6 nF but these were distinctly bimodal with a group at 8nF and a group at 12nF 20 and 20 each 222 (2.2nF): 1.36 +/- .01 nF these appear to be identical to the next group 102 (1nF): 1.36 +/- .01 nF as above appear to be identical to the preceding group 471 (470pF): 612 +/- 5 pF 221 (220pF): 197 +/- 13pF 470 (47pF): 44.9 +/- 4 pF also bimodal 20/20 330 (33pF): 34.6 +/- 4 pF also bimodal 20/20 220 (22pF): 27.6 +/- 0.2 pF 100 (10pF): 10.3 +/- 0.5 pF also bimodal 20/20 So I am going to split the four bimodal groups and lump the two clearly identical groups and end up with 19 groups instead of 16. The lower values are closer to spec than the higher ones, but there is clearly some sloppiness in how these packages are put together. As before without a way to measure capacitance you are going to be lost.

There were a couple of values that I needed. But the kit stops at 1uF and its time consuming to search. Some are identified by a peelable stuck-on label which falls off easily.

The contacts are very inconsistent in terms of size and placement. Some barely have any metal on one end. One contact peeled off the cap when I soldered it to the board. Save yourself potential headaches due to failures and buy name brand capacitors.

The labeling is a little odd. No units, had to guess that "226" was 22×10^6 picofarads. Got me out of a jam, but I highly recommend one of the "Sample Book" assortments over a zippoc bag of cut tape. If you need the values listed, go for it, they were quality parts, just didn't fit my workflow as well as I'd like.
