Re: heat sinking resistors

[Dave-3]

I used the ohmite tch35p series of thick film resistors in my power
attenuator between k3 and transverters. They are 11x15mm but have a mounting
flange/hole

I apologize in advance, but the smartest guys I know are here.

I just received a few Ohmite thick film power resistors for an attenuator
I'm making,
rated 20 watts. They are 15mm x 10mm x 3mm. Obviously they have to be
heat-sunk
(heat-sinked?) if they are going to dissipate that much power.

How do you do this? There's no hole in the middle...I can just clamp them
between a couple
of pieces of aluminum, but is there a right way to accomplish this?
