What resistor is this?

its 1/8" and what resistor can i use to replace it.

Use this to determine... or a multimeter. I can't tell from the camera and light you use.

red, green, silver, gold, = 0.25 ohm

Re: What resistor is this?

red, green, silver, gold, = 0.25 ohm

its Purple not red.

Re: What resistor is this?

is their a replacement for this at like, radioshack persay?

Here is what i need it for Power supply board.

Re: What resistor is this?

its Purple not red.

violet, green, silver, gold, = 0.75 ohm 5% tollerance
I am from UK, but your radioshack is like our maplins from what I have read on the forum, (not much good) but I guess you would get it there

have you tested other components out?
another failed component possibily caused that failure

Re: What resistor is this?

i don't see any 0.75 ohm 5% tollerance at radioshack unless i am blind.\ and i am pretty sure i caused the failure

Re: What resistor is this?

what resistors could i put in parallel to get 0.75 ohm 5% 1Watt or 2Watt

Re: What resistor is this?

I sincerely doubt it's a 0.75 ohm resistor. It's more likely to be red,green, orange or yellow which is 25 x 1k/10k = 25kOhm or 250kOhm, with a +/- 5% tolerance. Look up at the picture, ignore the third column of colors - your bars are 1st digit , 2nd digit, multiplier and tolerance.

If you still have doubts, I suggest looking up a resistor with the same color combination on the board , desolder it and go to Radioshack with both. If you can't find similar one just go with the burnt one - maybe it's still good.
They should have there a multimeter that can test the resistance and tell you the exact value.

Or just ask for 25 kOhm, 250 kOhm and whatever else you think it may be, they're a few cents each. Then match the color bars.

Its a 1 watt 0.75 5% violet, green, silver, gold you can see the colors in the picture.

I agree.

V,
Just for the record, Radio Shack is not exactly useful for parts like this.
Ten ohms, sure, one ohm, not too likely.

Fractional ohm, most consumer meters can't read it with any degree of luck.

In our business sometimes you have to break down and actually buy the correct part from a supply dealer. Or you can piss away hours trying to cludge up something that half works.

Boils down to how much your time is worth to you.
Dollars or hours.

Much luck.

Re: What resistor is this?

I use my ESR meter on low value resistors... works great.

Re: What resistor is this?

heh that resistor is shot. i bought 100 of them off ebay for 5$ http://cgi.ebay.com/ws/eBayISAPI.dll...#ht_500wt_1413

pretty good deal considering the main companys want 7-9$ just for shipping alone

Re: What resistor is this?

Okay so i got the resistors changed one in and it blows instantly once power hits the board, could a mosfest or something be causing it to short out instantly?

Re: What resistor is this?

Quite possibly, or you read the colour code wrong.

If you're sure the colour code was right (If you're having doubts, read the thing outside on a sunny day) then it could well be something else is shorted\faulty and is making the resistor blow.
