These high frequency chip resistors are ideal for use in RF and microwave applications. The components are available in 14 standard case sizes: 0402 through 3838. they are available with single surface or wrap around terminations, and a variety of termination materials for solder mount epoxy bond, or wire bond applications. Construction material consists of either a alumina or beryllia body. The devices are optimized for 50 ohm characteristic impedance. Power ratings for the resistors range from 50 milliwatts up to 200 watts and a low return loss, up to 20 GHz.
