Bourns has announced a new POWrFuse high power fuse model series. The PF-K series is designed to meet ISO8820-8 standards for the protection of high-voltage accessory circuits in electric and hybrid electric vehicles. These circuits are found in a variety of applications including electrical energy storage, battery disconnect units and battery management systems.
These fuses support operation up to 500VDC and feature a 20kA at 500VDC interrupting rating and an extended temperature range of -55 to 125°C. Individual models within the PF-K series have current ratings from 15 to 50A and are available in bolt and PCB mounting options.
The latest POWrFuse EV fuses have been tested to Bourns’ internal automotive quality standards for environmental reliability, transient current cycling and device electrical and fusing characteristics.
