Tighter envelope for overcurrent protection

The PolySwitch family of resettable overcurrent protection devices has been extended to include the new RXE005 from Raychem Circuit Protection.

The PolySwitch family of resettable overcurrent protection devices has been extended to include the new RXE005 from Raychem Circuit Protection.

With an industry low 50mA hold current, this PPTC (polymeric positive temperature coefficient) device can protect closer to the actual operating current thereby providing the tightest envelope of protection ever offered in a radial-leaded PPTC device.

At 20C, the RXE005 will hold 50mA and has a trip current of 100mA.

It is 60V rated and is capable of interrupting up to 40A.

PolySwitch resettable devices are used to help protect equipment from downstream short circuits, overvoltages and other power faults.

The RXE005 device is designed for binary and analogue I/O protection, as well as for protection of industrial communications networks using such links as RS-485 and RS-232.

"The RXE005 was developed to meet the needs of designers in areas of sensor, actuator and communications connectivity", said Steve Zalewski, Worldwide Industrial Market Manager for the Raychem Circuit Protection division of Tyco Electronics.

"It provides protection for I/O and data communications lines at closer tolerances than ever before, with minimal impact on communication distance or signal clarity".

RXE series devices are available in straight lead or kinked lead configurations and are supplied in tape and reel packaging for compatibility with high-volume assembly equipment.

UL, CSA and TUV agency certifications are currently pending.
