Design Kits - Power Resistors

Bourns has combined its existing knowledge of RF design with thick film to create a range of 50 ohm terminations.

Typical applications include drop-in isolators or power amplifier circuits in the wireless infrastructure, broadcast or radar industries. Configurations are either flange mount with a lead attached or surface mount with a terminal for external lead attachment. A format for mounting directly onto a printed circuit board is also available.

Typical applications of Power Resistors include snubbers and current sensing in power supply and electric motor control such as electric welding, heaters, power steering and many more.

In order to obtain a Bourns' Design Kit please contact your local Bourns sales office or authorized Bourns distributor.
