Product Overview

The RXEF050 from TE Connectivity is a radial leaded PolySwitch resettable device. It provides engineers with more design flexibility. The higher voltage ratings allow this device to use in new applications and it is compatible with high volume electronics assembly.
  • Fast time to trip
  • Low resistance
  • UL, CSA and TUV approved
  • Hold current of 0.5A at room temperature
  • Maximum voltage of 72V
  • Maximum current of 40A
  • Trip current of 1A at room temperature
  • Maximum resistance of 1.17ohm at 20°C (1hr post trip)
  • Operation temperature range from -40°C to 85°C
  • UL94 V-0 flame retardant epoxy polymer insulation
This device is intended for protection against overcurrent or overtemperature fault conditions and should not be used when repeated fault conditions or prolonged trip events are anticipated.
Operation in circuits with a large inductance can generate circuit voltage (Ldi/dt) above rated voltage of device.
