TDK Corporation EPCOS surge arrester stack for telecommunications

Wednesday, 26 September, 2012 | Supplied by: Mouser Electronics


TDK Corporation’s EPCOS gas-filled surge arrester consists of a stack of five individual arresters and was developed to protect the power supplies of telecommunications equipment. Its rated DC operating voltage is 48 VDC plus 20% according to IEC 61643-11. A feature of the arrester is its quenching of an applied DC voltage.The arrester stack with a type designation of LN8-A1400DC-5 measures 16.3 x 8.4 x 8.9 mm3 and thus takes up significantly less space than five discrete arresters.

This protective component has a surge current capability of 20 kA at an impulse wave of 8/20 µs and 4 kA at an impulse wave of 10/350 µs. The arrester is RoHS compliant, conforms to climate category of 40/90/21 of IEC 600068-1 and is designed for operating temperatures from -40 to +90°C. With a low capacitance of less than 1 pF (1 MHz) and a high insulation resistance of more than 10 GΩ (100 VDC), this SMD component has negligible parasitic coefficients.

The LN8-A1400DC-5 arrester is also available on tape and reel for automated SMD placement with the type designation LN8A-A1400DC-5.
