Bourns® RF Power Resistors and Terminations Short Form Brochure

Bourns® RF Power Resistors and Terminations P roducts which are delivered as flange mounted (see How to Order) should be bolted onto a heat sink, (see Figure 1) making sure that thermal grease is applied to the bottom of the flange before installation. Both the flange and heat sink should be perfectly dry and clean of any oxidants before the grease is brushed on. The thermal Chip grease will have a high thermal TF conductivity and will facilitate the passage of heat between the power resistor and the heat sink by improving the contact between the two surface Flange areas. Bourns recommends a...
