Tyco Electronics Offers New PolySwitch TRW250-180

Tyco Electronics Power Components (Menlo Park, CA) announced a new Raychem Circuit Protection product, a coated version of its popular TRW250-180 Series of radial-leaded PolySwitch devices. The new PolySwitch TRW250-180 device provides resettable over-current protection with improved mechanical characteristics and dielectric voltage withstand capabilities compared to the uncoated TR250-180U device for main distribution frame modules; ADSL modems; and central office, customer premise and access network equipment.

The low-resistance, through-hole device offers a rated hold current of 180mA. The TRW250-180 device limits fault energy, enabling OEMs to design products that use less-expensive, smaller, lower-power components. In addition to interrupting potentially damaging power faults, the TRW250-180 devices are robust to ITU-T K.20/21/45 lightning surges, making them a suitable choice for protection of modems.

The TRW250-180 device is available in tape-and-reel packaging for compatibility with high-volume manufacturing, or in bulk quantities. It is also available in resistance-binned packaging for applications with more stringent line-balance requirements.

Available now, pricing is $0.30 each in volume with a lead time of eight weeks ARO.
