WISCO International (Bird - Convection and Conduction cooled loads, 2 to 500W)

Bird™s T-Series convection-cooled and CT- Series conduction cooled RF terminations (loads) feature high-quality, conservative power ratings, robust construction, and numerous connector options.
T-Series Terminations will operate at 120% of nominal power rating at 25°C and below. Conduction-cooled loads are rated for 100% power handling at 100°C, derating to 0W @ 150° C.

General Specifications

Impedance: 50 ohms, nominal. T and C Series

* CT-type devices require mounting to a heat sink capable of maintaining a 100 o C or lower flange temperature.

** Dimensions and weight are for reference only, and are nominal values for units with male N-type connector, or supplied connector

if N-type is not available. Form factor for higher power models varies from illustrated examples.
