Resettable Circuit Protector complies with IEEE802.3af.

Press Release Summary:




Surface-mount PolySwitch® SMD050-2018 provides resettable overcurrent protection for Voice Over IP and powered Ethernet equipment. Should any power control FET fail short, unit shuts down individual port and helps prevent system-wide power failure. Once fault condition and power are removed, device resets and allows affected equipment to return to normal operating conditions. Device helps overcome fatigue failures and unrecoverable nuisance tripping.

New PolySwitch® Device Helps Designers Comply with IEEE802.3af Specification for VoIP and Powered Ethernet Equipment



MENLO PARK, CA-November 13, 2002- Tyco Electronics announces Raychem Circuit Protection's new PolySwitch® SMD050-2018 resettable device for telecom and networking applications. The SMD050-2018 device helps provide resettable overcurrent protection for Voice Over IP (VoIP) and powered Ethernet equipment, and is designed to meet the voltage and hold current requirements of the IEEE802.3af Ethernet specification.

The SMD050-2018 resettable device is designed to help facilitate the development of reliable, carrier-grade VoIP systems. When installed between the power source and output of a powered Ethernet device, the SMD050-2018 device provides a second layer of defense in the power management circuit. Should any power control FET fail short, the PolySwitch device shuts down the individual port and helps prevent a system-wide power failure. Once the fault condition and power are removed, the device resets and allows the affected equipment to return to normal operating conditions. The SMD050-2018 device also helps overcome the fatigue failures, unrecoverable nuisance tripping, and installation problems associated with the alternative second layer solution - traditional single-use fuses.

"This device was developed in response to new circuit protection requirements as described in the IEEE802.3af powered Ethernet specification, and plays a key role in the design of carrier-grade, reliable, VoIP systems," said Adrian Mikolajczak, Multimedia Market Manager for Raychem Circuit Protection. "With an FIT of less than 0.01 when used at rated voltages, the PolySwitch SMD050-2018 device offers a new class of reliability and survivability in the field," he added.

The PolySwitch SMD050-2018 surface-mount device is available in tape and reel packaging for compatibility with high-volume manufacturing. For further information or technical assistance, call (800) 227-7040 or (650) 361-6900, or visit www.tycopowercomponents.com.
