Littelfuse introduced its new 977 series of ceramic body, 5 x 20 mm fuses designed for circuit protection in both high-power AC and power-efficient DC applications.
The fuses are rated at 450 V d.c. and 0,5 A to 16 A. They can safely interrupt fault currents up to 100 A at 500 V a.c. or 200 A at 450 V d.c. This series also includes axial lead versions, making it ideal for PCB through-hole mounting. Electronic designers will appreciate the ability to use these fuses in power supply lines both before and after the PFC (power factor correction) capacitor banks. On the DC side, their DC rating also makes them ideal for individual component and secondary circuit protection.
The 977 Series fuses are RoHS compliant and are designed for protection of equipment such as three-phase power supplies, uninterruptible power supplies and motor control circuits.
