TDK Corporation is presenting a new EPCOS gas-filled surge arrester consisting of a stack of five individual arresters. Developed specifically to protect power supplies in telecommunication 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.
The arrester stack with a type designation of LN8-A1400DC-5 measures a compact 16.3 x 8.4 x 8.9 mm3 and occupies significantly less space than five discharge 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 corresponds 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 (100V 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 LNB8A-A1400DC-5.
