Telecom protection improved

10 September 2003 Circuit & System Protection Perimeter Security, Alarms & Intruder Detection

Epcos has launched two completely-new PTC thermistor designs for telecom line protection.

The new square PTC thermistor R212 is designed for the latest generation of main distribution frame modules. With overall dimensions of only 5,95 x 5,95 x 2,65 mm, it is intended for vertical surface mounting. Its electrodes are suitable for soldering as well as for clamping. Rated resistance is 12 Ω at 120 mA and 25°C.

There is a distinct trend in line card design toward miniaturisation and simplification. The telecom pair protector (TPP) is an innovative line protection module containing two Epcos PTC thermistors in a four-pin case. It can be processed by automatic SMD placement machinery and save up to 40% of the space required by previous SMD solutions.

An insulation strength of 3000 V is maintained between the two thermistor disks, and the two PTC thermistors are resistance-matched, ensuring balance between lines. The TPP can be equipped with various PTC thermistor disks and thus cover a wide resistance range.
