MA 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.
