Hi all
10 Series | Ohmite Mfg Co
What about using this resistors for emitters in a Poweramp?
They are non inductive, less then 100ppm TC for 0.2 Ohm for 3 and 5 Watt types
Are they suitable for this application? Any experience?
low inductance is important, so for me wirewounds cannot be used there . And all the metal foil types have 200-300 ppm TC at >3Watt

Yes, these should be fine for emitter resistors. They're only available up to 0.25 Ohms, though.

This thread is old, but maybe someone will pay attention to it.
Looking for .18 5W output emitter resistors for an amp I am assembling, I found these current sensing types.
BPR58CR18J KOA Speer | Mouser
They are smaller than the other .18 5W at Mouser, and cheaper.
Temp PPM is higher than the option.
Which would be the recommended brand and model for this type of resistor that is not too long?

Even wire wound resistors aren't very inductive as they are counter wound on themselves to cancel out the inductance.
Only true for some wirewounds.nigelwright7557 said:Even wire wound resistors aren't very inductive as they are counter wound on themselves to cancel out the inductance.
