140V Mod Resistors

Got my resistors in the mail today from Digikey. They look quite a bit smaller than the ones I saw in pictures on here. Just wondering if I ordered the right ones, I have to 100V IDM, I ordered the 75K Ohm 1/2 watt 100% tolerance. Just wondered why they looked so small. Thanks

In the electronics world. size doesn't always matter. =)

I have 75k ohm metal film 50w 1% tolerance here.

Thats what the package says.
I think it means half watt though. Duno why its printed like that.
oh, i look with magnifying glass, it has period. haha. .50watt

I sent 2 to Jleal, I wonder if he ever got the mod done.

Some of them are the bigger size, some are smaller. Mine was done with a larger size one. They'll work the same. Just be careful soldering and make sure it's secured with some hot glue or silicone to keep the resistor from vibrating.

it shouldn't' go anywhere if you have a gold solder joint, but it sure wasn't easy to solder.

I thought I wrote an article on my page, but apparently I haven't yet.
Ooops. Sorry.
