RA Series - Low Profile Varistor

The RA Series transient surge suppressors are varistors (MOVs) supplied in a low-profile box that features a precise seating plane to increase mechanical stability for secure circuit-board mounting. This feature makes these devices suitable for industrial applications critical to vibration. Their construction permits operation up to 125�C (ambient) without derating.

The RA series are available in voltage ratings up to 275V V M(AC)RMS and energy levels up to 140J.
These varistors are used in automotive, motor control, telecommunication, and military applications.

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)	230
This is the maximum continuous DC voltage, which may be applied to the device. Close Info	Max Rated DC Voltage	300
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)	20
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)	1200
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)	360
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)	324
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)	595
This is the maximum 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	VNDC MAX (V)	396
