Some help identifiying a resistor

[zomi]

Had csi 825 hot air station go bad.
Getting bad readings on this resistor
Could do with some help identiying the rating

Re: Some help identifiying a resistor

So its

Brown Black Gold GOld

1ohm resistor

Its massive through
3cm wide

Its been used as a fuse resistor

Any recommendations on where to source repalcement

Re: Some help identifiying a resistor

1ohm 5%
wattage will depend on size.
it's a flameproof type btw.

http://www.maplin.co.uk/p/wirewound-...m-resistor-h1r

will that replace it ?

Its 24mm Length

8mm width

Re: Some help identifiying a resistor

If it's used as a fuse resistor you may have a short somewhere else too.

Source from wherever you like. eBay, Farnell, Digikey, etc.

That one you linked to should be fine, but it's not going to fail like a fuse in the same way as the old one did on overload. You may wish to add a real fuse in series as well.

Re: Some help identifiying a resistor

The element blew out
And took the fuse resistor with it..
A glass fuse ?

thanks for the info guys

Re: Some help identifiying a resistor

dont use wire-wound - they are inductive.

use metal film type

Re: Some help identifiying a resistor

Glass is OK, ceramic is better.

Would the inductance of a wire-wound resistor really matter here, given that the heating element is probably coiled and has its own parasitic inductance anyway?
