Today I learned how to interpret the values of trim pot resistors based on the printed text.
Back story: I recently found the wonderful world of cheap eBay electronics. This weekend I finally sat down with some trim pot variable resistors and learned that the 130 pieces I purchased were in separate bags for a reason. There are 13 different base resistance values … which I promptly mixed together in a fit of ignorance.
Fast forward to the internet and some searching and I now know how to interpret the three numbers printed on each. For example:
502: 50 x 10^2 or 50 x 100 or 5,000 Ohms
502 would be a 5 kΩ
