TDK announces EPCOS gas-filled surge arrester for telecommunications equipment
TDK today announced the launch of a new EPCOS gas-filled surge arrester. The EPCOS gas-filled surge arrester consists of a stack of five individual arresters and is developed specifically to protect the power supplies of telecommunications equipment. Its rated DC operating voltage is 48 V DC plus 20 percent according to IEC 61643-11. The special feature of this arrester is its reliable quenching of an applied DC voltage. 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 conforms to climate category of 40/ 90/ 21 of IEC 600068-1 and is designed for operating temperatures from -40 to +90 °C. With an extremely low capacitance of less than 1 pF (1 MHz) and a high insulation resistance of more than 10 GΩ (100 V DC), this RoHS-compatible 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.
