Fujitsu Components America Inc. offers a new 20A power relay in a slim package, measuring 30.1-by-15.7-by-23.3mm, for commercial and industrial products. The FTR-K3 1 Form A relay touts a nominal operating power of 780mW, which is the lowest power consumption in its class, said the company.

Rated for a maximum load of 20A at 250Vac, the new is suited for switching compressor and inverter loads in air conditioners, refrigerators and other appliances, as well as for use in office equipment.

The FTR-K3 relay provides an 8mm clearance distance and a minimum 9.5mm creepage distance between coil and contacts for high-insulation resistance. Key electrical features include a 1,000V dielectric strength between contacts and 5,000V dielectric strength between coil to contact. It also has a surge withstand voltage of 8,500V minimum (1.2 x 50?s standard waveform). The operating temperature is -40C to 60C.

The relay's expected mechanical life is rated at 2 million operations. It has an electrical life of 100,000 operations at rated load (20A, 250Vac, Cos Phi 1).

The relay meets UL, CSA, VDE (pending) and CQC agency approvals. It uses UL94 flame class V-0 and UL CTI level class 2 plastics, and is constructed of lead-free materials and cadmium-free contacts to meet international environmental requirements.

The FTR-K3 series will be available in second half of 2004 with #250 TAB and PC-board terminals in 5-, 6-, 9-, 12-, 18- and 24Vdc coil voltages. Samples are available immediately. A FTR-K3 with a 12Vdc coil is priced at $1.10 each in quantities of 100,000. Delivery is 12 weeks.
