Metal Oxide vs Wirewound Resistors

[alice]

I can get 5W resistors in wirewound or metal oxide. Any particular difference between the two? I am using them for B+ rail and/or cathode resistors for the power stage.

[Old Tele man]

...most metal oxide resistors are "flame proof" (good)

...while most wirewound resistors can be "inductive" (not good) due to their constrution.

Both are flameproof. Wirewound resistors DO exhibit some inductance by the sheer fact that they a coil of wire wound on a ceramic form, not necessarily a bad thing. I limit their use to power supplies, screen grid resistors and cathode-bias resistors. There is no other place they would really be needed.

thanks for the info.

to paraphrase...

...most metal oxide resistors are edit-"cheap"-edit (good)

...while most wirewound resistors can be edit-"less cheap"-edit (not good) due to their constrution.

go metal oxide!
