New Small Form-Factor Polyswitch Device Designed for Customer Premise Equipment


MENLO PARK, Calif. -August 5, 2004- Raychem Circuit Protection, a business unit of Tyco Electronics, announces its new PolySwitch TRF600-150 circuit protection device for telecom and networking applications. The new device is 25% smaller than the previous version and helps provide resettable overcurrent protection in telephones, fax machines, set-top boxes, security systems, modems, and other telecommunications equipment that must comply with UL 60950 and TIA-968-A standards.

The new PolySwitch device features a tighter resistance window and lower post-trip resistance than its predecessor, theTR600-150 device. The smaller physical dimensions of the device facilitate development of more densely populated PCB designs and permit drop-in replacement for existing designs. In addition, the new TRF600-150 device utilizes a lead (Pb)-free construction that is compliant with RoHS (Reduction of Hazardous Substances) Directive 2002/95/EC.

When compared to traditional lightning-robust fuses that do not interrupt until fault currents exceed 1A, the resettable TRF600-150 device offers a 150 mA hold current and limits let-through energy to significantly lower levels. This permits the use of smaller, less expensive, and lower-power handling circuit components. In addition to interrupting potentially damaging power faults, the PolySwitch TRF600-150 device is robust to ITU-T K.20/21/45 lightning surges, making it an appropriate choice for protection of telecom and networking equipment designed for use around the world.

"This new product was developed in response to customer requests for smaller devices that could be used in space-constrained customer premise equipment that requires compliance with UL 60950 and TIA-968-A," said Boris Golubovic, telecommunications market manager for Raychem Circuit Protection. "In addition, we have responded to the industry demand for Pb-free devices with this new RoHS-compliant, PolySwitch device."

The TRF600-150 device is available in tape and reel packaging for compatibility with high-volume manufacturing, or in bulk quantities. For further information or technical assistance, call (800) 227-7040, or visit www.circuitprotection.com.
