Resistors

Mine have1 brown and 3 red, that one has 1 brown, 3 black and another brown?

While I'm here I want to thank all of you for your input..

thanks all

The link should take you to a 2200 ohm resistor. ±1% And 600mW. I think that's RED RED RED BROWN. im just going from memory thow, someone correct me if i am wrong.

CLICK HERE. To see the specks.

I ordered 250, dose the size deference seem right?  How do I know what watt the old resistors are rated?The old ones read 2.20K and the new ones read 2.18K, I guess that is good but I'm worried about the watt rating.

Rightly so.  Resistors have gotten a little smaller per Watt rating over the years, 'cause they can run a little hotter.  But maybe not this much.  If you had less resistors to replace, I'd tell ya to use four new resistors/resistor.  Any integer square number of equal-valued resistors can be used to make a more power-tolerant version.

You can measure the physical dimensions of your resistors and compare them to ones in an old e- catalog.  Just to glance at the situation the resistors you have look like half-watters and your replacement ones look like quarter-watters.  Too big is better than too (contemporaneous w/ your device)  small in most cases.

if your concerned with the smaller resistors then connect 2 in series with 2 in parallel, this will end up with the same value within the tolerance of the resistors but it will handle much more power

this would require 4 resistors for every one your replacing

alternatively get higher wattage resistors

If you had to guess, what wattage would you say the old resistors are?

1/2 watt?

What is the wattage of the new ones ?

Hi all,

The new one are what Lupe Lopez gave me a link to: http://www.newark.com/vishay-bc-components/mrs25000c2201fct00/resistor-thin-film-2-2k-0-6w-1/dp/97K5580, Thanks Lupe....

They are 600mW and if a 1/2 watt is: 500mW and what I have (the old ones) are a 1/2 watt then I should be good to go. I guess there is no way to know what watt my old ones (in photo on the board) are?

I think I'm good with these Lupe just wanted to post the size difference and get some feed back, this board was made in the early 80's
