Metal-Oxide Varistors (MOVs) Axial Lead / Application Specific Varistors > MA Series MA Varistor Series RoHS 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 • Lead–free, Halogen- • Available in tape and reel or bulk packaging Free and RoHS None • No derating up to compliant. 85ºC ambient • 3mm diameter disc size • New black epoxy offers Additional Information • Small axial lead package improved performance • Wide operating voltage for high temperature range: Lead-free wave V 9V to 264V soldering process.
