New TB-P and TL automotive power relay

With Panasonic’s new power relays TL (product number: ACTL3CR3C) and TB1 (product number: ACTBPDH4C), junction box manufacturers are able to reduce the size of smart junction boxes by replacing plug-in relays with space-optimized pc board relays.

The new TL relay has a fuse rating of 40A and only requires a board space of 158,4mm² with its outline dimensions of 14.4mm x 11.0mm. This is 12% smaller than comparable 40A PCB relay solutions on the market. For applications requiring lower currents, the TB1 power relay can save up to 28% space on the PC board compared with other solutions with outline dimensions of only 14mm x 9,2mm and required space of only 128.8mm². By combining both relays, designers of smart junction boxes are able to realize an optimized space-saving design. Typical high-current applications in smart JB for Panasonic’s new TL relay are fan motors, ignition, and starter motor solenoids. The TB1 relay is optimally suited for applications like air conditioning (A/C), magnetic clutches, fuel pumps, fog lamps, electric gasoline injection (EGI) and defoggers.
