Metal-Oxide Varistors (MOVs) 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. Agency Approvals Features Agency Agency File Number Leadfree, Halogen- Available in tape and reel or bulk packaging Free and RoHS None No derating up to compliant. 85C ambient 3mm diameter disc size New black epoxy offers Additional Information Small axial lead package improved performance for high temperature Wide operating voltage Lead-free wave range: soldering process.
