Series: MA Questions? Contact Littelfuse Support
MA
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 Ratins and Specifications table for part number and brand information.

Features:
  • 3mm diameter disc size
  • Small axial lead package
  • Wide operating voltage range: VM(AC)RMS 9V to 264V VM(DC) 13V to 365V 
  • Available in tape and reel or bulk packaging 
  • No derating up to 85ºC ambient 
  • New black epoxy offers improved performance for high temperature Lead-free wave soldering process

AN9768 Transient Suppression Devices and Principles

This application note discusses the two major categories of transient suppressors: a) those that attenuate transients, thus preventing their propagation into the sensitive circuit; and b) those that divert transients away from sensitive loads and so limit the residual voltages.

AN9769 An Overview of Electromagnetic and Lightning Induced Voltage Transients

This application note is an overview of the sources and nature of various transient overvoltages, and the problems that may result.
