They're not wirewound. They consist of a thin film of metal deposited on
a ceramic tube, which is helically cut to leave a conductor in a spiral
pattern. A wirewound resistor has a lot of inductance because it's made
of many turns of wire. A metal film resistor has a very small amount of
inductance by comparison -- so little that it can be ignored for most
purposes.

are metal film resistors wirewound or not? I've been trying to find this one
out. Someone who I know says they're not so are suitable for RF but Maplin
catalog seems to say they are.


someone please help!
