Medium Power Multilayer Chip Varistor

Transient Voltage Suppression, ESD Protection Devices & EMI Devices

TELECOM SERIES - VC14 (1812)

FEATURES

• Pd/Ag Terminations

• High Energy Ratings (up to 6 Joules with 1812 case)

• Multiple Strike Capability

• Provides EMC Capacitance

• Effective Alternative to Leaded MOVs between 60-90Vrms

• Specified in accordance to CCITT 10/700ms Pulse test

CCITT 10x700µs TEST

A test pulse of 10x700µs duration as specified by CCITT or

IEC 61000-4-5 is often used to check the interference

immunity of telecom equipment.

The curves show that the 60Vrms varistor can reduce the

interference voltage at the equipment connected from 2kV

to less than 200V.

TARGET APPLICATIONS

• Phone Lines, ADSL Lines, and other Telecom Circuits

• Consumer Products

Ten pulses with a duration of 10x700µs applied at one

minute intervals are specified for telecom equipment.

The curves show the V1mA drift when more than 10 pulses

are applied.
