Telecom series

Here are some construction of the Telecom series. Telecom series has round varistor element, leaded, the coating of Telecom series is epoxy resin, flame-retardant to UL 94 V-0 and the terminals of Telecom series is tinned copper wire.

Here are some features of the Telecom series. The Telecom series is suitable for handling the surge current of the 10/700s pulse to ITU-T and IEC 1000-4-5, and Telecom series is also suitable for handling the increased surge voltage according to the directives of Germany's telecom administration. The Telecom series matched to line conditions with or without superimposed ringing voltage. The Telecom series has electrical SMD equivalents available and PSpice models.

Here are some general technical datas of Telecom series. The climatic category is made up of LCT which is 40 , UCT which is + 85 in accordance with IEC 60068-1and Damp heat, steady state(93 % r.h., 40 ), which is 56 days in accordance with IEC 60068-2-3. The operating temperature is 40 to + 85 in accordance with CECC 42 000.The storage temperature ranges from 40 to + 125 , the electric strength is 2,5 kVRMS in accordance with CECC 42 000
insulation resistance is 10 M in accordance with CECC 42 000, and the response time is < 25 ns.

Here are some maximum ratings of Telecom series when TA is 85 .
