Fujitsu relay has metal casing

Fujitsu Components Europe has released the FTR-B3-RF, an ultra-miniature high-frequency relay with a metal case.

The shield around the relay reduces the loss of RF signals and its effect on other components on the board.

At the same time the metal 'armour' of the relay protects it from unwanted signal radiation from outside.

The FTR-B3-RF is designed with good high-frequency characteristics up to 1 GHz (Impedance 50 ohm), which makes the FTR-B3-RF suitable for low signal switching applications such as measuring and medical equipment.

FTR-B3-RF features the following high-frequency characteristics: Isolation: > 30dB; Insertion loss: < 0.2dB; VSWR: < 1.2.

The FTR-B3-RF features a Two Form C contact utilising high reliable bifurcated contacts.

The relay has surface-mounted terminals and measures 6.7mm (height) and 97mm (mounting area).

The relay offers RF switching power of 3W at 1 GHz and RF carrying power of 1W at 1 GHz.

Another main feature of the FTR-B3-RF is its low power consumption.

The standard type has a power consumption of 140mW (230mW at 24V), while the latching type offers a power consumption of 100mW (120mW at 24V).

Target applications include: measuring equipment; multiplex wireless equipment; data transmission equipment; digital service units for ATM; medical equipment; radio equipment; general RF low signal switching; and RF attenuators.
