Ultra-silent 10 A relay provides high insulation in a small package

21 March 2007 Switches, Relays & Keypads

Fujitsu Components Europe has released a 10 A power relay with a maximum noise level of 50 dB for use in sophisticated consumer appliances, such as digital televisions. An internal U-shaped spring enables the relay’s low noise level even when mounted on a PCB.

The FTR-H3 is a 1 Form A relay with a switching voltage of 400 V a.c. and 300 V d.c. It carries a 78 A inrush rating, and features 8 mm clearance distance between coil and contacts for high-insulation resistance. This silent relay has dimensions of 28,8 x 13,7 x 18,8 mm (LxWxH). It comes in standard coil voltages of 5, 9, 12 and 24 V d.c. and features 530 mW nominal power.

With an electrical life of 100 000 operations at rated load (10 A, 250 V a.c.), the relay meets TV-5 standards. It also meets UL, CSA and VDE certifications. The FTR-H3 has an operating temperature range of -40 to 75deg;C. It has a surge withstand voltage of 10 000 V (min.) and features 5000 V a.c. dielectric strength between coil and contacts. The expected mechanical life is 2 million operations.

The FTR-H3 is constructed of RoHS-compliant materials, cadmium-free contacts and bromine-free plastic to meet environmental disposal program requirements.
