CH Surface Mount Varistor Series

CH series transient surge suppressors are small, metal-oxide varistors (MOVs) manufactured in leadless chip form. They are intended for use in a variety of applications from low voltage DC to off-line board-level protection. These devices, which have significantly lower profiles than traditional radial-lead varistors, permit designers to reduce the size and weight and increase the reliability of their equipment designs.

Ch series varistors are available in a voltage range from 14V to 275V V M(AC)RMS , and energy ratings up to 23J.

This is the maximum continuous sinusoidal voltage, which may be applied to the MOV. This voltage may be applied at any temperature up to the maximum operating temperature of 85°C. Close Info	VMAX AC (V)	250
This is the maximum continuous DC voltage, which may be applied to the device. Close Info	Max Rated DC Voltage	330
This is the maximum rated transient energy, which may be dissipated for a single current pulse at a specified impulse and duration (2µs), with the rated V_RMS applied, without causing device failure. Close Info	Surge Energy (WTM) (J)	7
This is the maximum peak current, which may be applied for an 8x20µs impulse, with rated line voltage also applied, without causing greater than 10% shift in nominal voltage. Close Info	Peak Pulse Current (I_TM) 1xAmps (A)	250
This is the voltage at which the device changes from the off state to the on state and enters its conduction mode of operation. This voltage is characterized at the ImA point and has specified minimum and maximum voltage ratings. Close Info	Nominal DC Voltage (V_NDC) (V)	390
This is the minimum voltage at which the device changes from the off state to the on state and enters its conduction mode of operation. This voltage is characterized at the 1mA point and has specified minimum and maximum voltage ratings. Close Info	V_NDC MIN (V)	354
This is the peak voltage appearing across the MOV when measured at conditions of specified pulse current amplitude and specified waveform (8x20µs). Close Info	Max Clamp Voltage (Vc) (V)	650
