Axial Lead
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.
