Menlo Park, Calif. Developed in response to customer requests for smaller devices that can be used in space-constrained customer premise equipment, Raychem Circuit Protection, a business unit of Tyco Electronics, has launched its new PolySwitch TRF600-150 circuit protection device for telecom and networking applications. The new lead-free 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 resettable TRF600-150 device offers a 150 mA hold current and limits let-through energy to significantly lower levels than traditional lightning-robust fuses. This permits the use of smaller, less expensive, and lower-power handling circuit components, said the company. In addition to interrupting potentially damaging power faults, the PolySwitch TRF600-150 device meets ITU-T K.20/21/45 for lightning surges, making it suitable for protection of global telecom and networking equipment.
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 aids in the development of more densely populated PC-board designs and permits drop-in replacement for existing designs, said the company. The device is compliant with the RoHS (Reduction of Hazardous Substances) Directive 2002/95/EC.
Available in tape and reel packaging or in bulk quantities, the TRF600-150 device is priced at $0.35 in quantities of 100,000. Delivery is four to six weeks.
