Automotive relay suits EV/PHV on-board charging
Fujitsu Components America is sampling a 6.6kW (32A, 250V AC) switching automotive relay for on-board battery chargers in electric and plug-in hybrid vehicles (EV/PHV).
The FTR-K5 is a 1 Form A PCB relay series, claimed to assist with faster EV/PHV battery charging while also meeting automotive vibration and shock resistance specifications. It has a 105 degrees C temperature rating and 8.0mm insulation distance between coil and contact; characteristics that exceed those of any currently available power relay in this class, says Fujitsu.
The relay features a 5,000V AC withstand voltage between coil and contact and 1,000V AC between adjacent contacts. Despite its low power consumption of 900mW, the relay can sustain a 40A continuous power supply (without switching).
The FTR-K5 series is available in either a flux-free or plastic-sealed enclosure. The flux-free version has a life of 30,000 operations and is recommended for sealed charger units. The plastic-sealed type has a higher resistance to dust and exhaust gas, making it suitable for non-sealed charger units.
Volume production of the FTR-K5 series is expected to begin in March 2020.
Fujitsu Components America markets and distributes electronic and system components and sub-systems throughout North and South America. Its product range includes relays, connectors, input and pointing devices, touch panels, thermal printers, and wireless modules.
The company is headquartered in San Jose, California, USA.
