Littelfuse PolySwitch RXE Series 1.6 A Resettable Fuse 72V Radial Lead RXEF160

Littelfuse RXEF160 resettable fuse from the PolySwitch RXE Series features a hold current of 1.6 A and a voltage rating of 72 V, designed for overcurrent protection in electrical and electronic circuits. This radial lead fuse automatically resets thousands of times after fault conditions, eliminating the need for replacement and reducing maintenance.

The device has a trip current of 3.2 A and a fast trip time of 11.4 seconds, providing rapid response during overloads or short-circuit events. Its compact dimensions (16.3 mm length, 20.8 mm height, 3 mm width) make it suitable for PCB and wire-ended applications.

Operating reliably within a temperature range of -40°C to 60°C, it dissipates 1.9 W of power efficiently. Its low resistance (minimum 0.09 Ω, maximum 220 mΩ) ensures minimal impact on circuit performance. The fuse meets multiple international standards including CQC, RoHS, TUV, UL, and CSA, making it suitable for global markets.

Common applications include protection circuits in printers, satellite video receivers, industrial controls, transformers, computer motherboards, modems, USB hubs, peripherals, game machines, phones, fax machines, analog and digital line cards, security systems, power supplies, automotive and medical equipment, instrumentation, control systems, computers, audiovisual devices, and telecommunications.

Provides automatic reset capability thousands of times, eliminating fuse replacement. Compact radial lead design suitable for PCB wire-ended mounting. Low hold current of 1.6 A with a trip current of 3.2 A ensures circuit protection.

Voltage rating up to 72 V supports a wide range of applications. Fast time to trip of 11.4 seconds minimizes damage during overload conditions. Operating temperature range from -40°C to 60°C allows reliable performance in varied environments.
