A resistor can't be both. A resistor can have both gold and silver bands since they are both valid multiplier coefficients as well as tolerance. See https://www.digikey.com/en/resources/conversion-calculators/conversion-calculator-resistor-color-code for an example of the resistor colour code. [Edit] Just re-read the thread and Pandora stated as much. Edited June 30, 2022 by Crosland Clarification Link to comment Share on other sites More sharing options...

Every single on on a number of PCBs on my desk in front of me have bulges at the ends. The only definitive proof is to know more about the circuit where it came from. The ones in the original post look like ferrite bobbins with ends of the winding wire wrapped & soldered around the connecting leads. The coating smoothes out the general shape. The overall shape with such a pronounced bulge cries inductor to me. Link to comment Share on other sites More sharing options...

Not really but it would have been nice to get some understanding of the application and the fault that created the problem. Those were requested. Otherwise it's just an open-ended question with no definite answer. Link to comment Share on other sites More sharing options...

StuartMc Posted July 4, 2022 Share Posted July 4, 2022 Reminds me literally about 40 years ago at school my friend came up with a better mnemonic for the resistor colour codes 0-9 Quote Bye Bye Rosie Off You Go Back Via Great Western Black Brown Red Orange Yellow Green Blue Violet Grey White I don't know if I've ever actually used it to identify a resistor (a digital voltmeter is just so much quicker), but it certainly worked as far as remembering the sequence goes! 1 Link to comment Share on other sites More sharing options...

AndyID Posted July 4, 2022 Share Posted July 4, 2022 The problem with resistors is "there are so many to choose from" 😀 After years of fumbling around in packets and drawers looking for a particular value I came up with this really hi-tek solution - 1 Link to comment Share on other sites More sharing options...
RMweb Premium melmerby Posted July 4, 2022 RMweb Premium Share Posted July 4, 2022 What's wrong with drawers? I have one like this: https://www.screwfix.com/p/50-drawer-metal-storage-unit/5616p 2 values per drawer (with divider) all labelled. I've another next to it with capacitors (lower number of values!) semiconductors, IC sockets, general LEDs etc. I've got some secondary storage in a different location using one of these: https://www.rapidonline.com/raaco-136242-handybox-55x4-14-0601 It has removable inserts of varying sizes to suit the components. That contains Arduinos and other similar items, displays, sensors & other modules, specialised LEDs etc. It's used when developing projects. Raaco organisers are also very good for storing model railway stuff such as all my various wheels, motors, gearboxes etc. Link to comment Share on other sites More sharing options...
