MA Varistor Series
Axial Lead / Application Specific Varistors > MA Series
Specifications are subject to change without notice.
Please refer to www.littelfuse.com/series/ma.html for current information.
Should transients occur in rapid succession, the average power
dissipation required is simply the energy (watt-seconds) per
pulse times the number of pulses per second. The power so
developed must be within the specifications shown on the
Device Ratings and Specifications table for the specific device.
Furthermore, the operating values need to be derated at high
temperatures as shown above. Because varistors can only
dissipate a relatively small amount of average power they are,
therefore, not suitable for repetitive applications that involve
substantial amounts of average power dissipation.

NOTE: If pulse ratings are exceeded, a shift of V
N(DC) (at specified current) of more than
+/-10% could result. This type of shift, which normally results in a decrease of V
N(DC), may
result in the device not meeting the original published specifications, but it does not
prevent the device from continuing to function, and to provide ample protection.
