Varistor Products Axial Lead / Application Specific Varistors > MA Series RoHS MA Varistor Series Description The MA Series of transient surge suppressors are axial lead Metal Oxide Varistors (MOVs) for use in a wide variety of board level industrial and commercial electronic equipment. They are intended to protect components and signal/data lines from low energy transients where the small axial lead package is required. The MA Series is offered with standard ('S' suffix) or tightened ('B' suffix) clamping voltage. See MA Series Device Ratings and Specifications Table for part number and brand information.

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.

This type of shift, which normally results in a decrease of VN(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. ©2008 Littelfuse, Inc.
