What kind of resistors are these?

Safe_Cracker · 31st December 2007, 04:29 AM

I need to replace a few of these( green raised ones), I know the values but what kind are they exactly? Someone said they might be flame proof just want to replace them with exact matches. Thanks... Polo.

Those are Metal Oxide Film Resistor See pictures

These seem to be 2.2 ohm fuse resistors. They are supposed to always become an open circuit before burning in case of overload.

BTW: Why did they fuse?

Thanks for the answer. They didn't, I am replacing 16 output fets on this DD Z1a monster when I noticed that the manufacture for some reason changed the original resistors with different ones without removing it from its heatsink, kinda crappy work. It will work but since it is out I will be changing them for asthetic reasons on my part. Also these are the same? Polo..

Those resistors would probably be classified as flameproof. Resistors designated as fusible resistors would have a black band.

As stated before, they are probably metal oxide film resistors.
