Metal Oxide resistors in Oz

GK · 17th June 2009, 06:24 AM

Does anyone out there know of an Aussie distributor of 3W/5W low value (>0.1R) metal oxide power resistors such as these:

http://au.mouser.com/Search/ProductD...lbrt5DpCbLg%3d

I can't find any (from Farnell, RS, etc, etc) less than 10R. I'm not looking to buy 1,000,000 pcs either.........

Semtronics has the 2 watt ones. Might be worth giving them a call.

Have you tried rockby.com.au ?

Hi Col.

Those metal film's from Semtronics only start at 1 ohms. Metal film and metal oxide resistors in the 0.1R - 0.91R range a damn hard to find in any power rating.

The Rockby site drives me mental - click 'resistor' and you get five million hits, 10 visible on screen at a time.

yeah the rockby web interface is non-user friendly. It's often worth giving them a call though. How about radio parts?

Howdy Glen,

Not exactly what you asked for as they're 10w, and there are only a few values...

...but just in case they're just what you need!

These are damn nice if you can get them......not cheap though.

I'm not sure why you want metal oxide. When I need low values I use current sense resistors.

Well I need over 100 of them and I need 0.22 ohms, not 0.022 ohms.

The 5W metal oxide resistors are ~1/3 the price in an order multiple of 100.

Sorry, I misunderstood what you were asking.
