Broadband Relays with Coil Diode Options

Mon, 07/12/2010 - 10:41am
Teledyne Relays has introduced the RF300D/RF303D & RF300DD/RF303DD series. These new ultraminiature broadband TO-5 relays, have internal discrete silicon diodes for coil transient suppression (D) and polarity reversal protection (DD). The diodes are built in to the relay to reduce the number of external components needed to drive the relays, and reduce the circuit board space needed to mount the relays to a minimum.

Designed to operate in the DC to 6 GHz frequency range or with high speed digital signals, the relays are exceptionally stable with excellent switching repeatability over a life of 10 E 7 operations at signal level.

Applications include test & measurement, low power switching matrices, low power wireless and semiconductor test and load boards.

Enclosed in a 9.4 mm diameter hermetically sealed washable package, the Series offers 5V and 12V coils with power consumption is 450 mW for RF300 versions and 200 mW for the sensitive RF303 versions. Continuous operating and switching performance is offered over a temperature range of -55°C to +85°C.
