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.
