Tyco Electronics Unveils SMD050-2018 PolySwitch Device
Tyco Electronics Power Components (Menlo Park, CA) announced Raychem Circuit Protection’s new PolySwitch SMD050-2018 resettable device for telecom and networking applications. The SMD050-2018 device helps provide resettable over-current protection for Voice Over IP 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.
The PolySwitch SMD050-2018 surface-mount device is available in tape-and-reel packaging for compatibility with high-volume manufacturing. Samples are available now. Pricing is $0.26 in quantities of 100,000. Delivery is 4 to 6 weeks ARO.
