Bourns® Innovative IsoMOV™ Protectors

 

As the most significant advancement in MOV design in decades, Bourns® IsoMOV™ hybrid protection components fully combine the classic GDT and MOV in a totally new design. This single-package solution provides a symbiotic relationship where the GDT blocks leakage currents through the MOV that would otherwise lead to premature failure of the MOV device. It also allows the MOV to prevent follow-on current after a surge that might damage the GDT.

Bourns® IsoMOV™ protectors offer:
  • High reliability and long life – including in certain harsh environments
  • Extended temperature range
  • Low leakage
  • Superior energy handling density
  • Graceful end-of-life failure mode
Boosting its design flexibility for engineers, IsoMOV™ protector surge ratings are comparable to the next larger size conventional MOV device. This gives designers the flexibility to select an IsoMOV™ protector that is smaller than the MOV option or upgrading to an IsoMOV™ protector of the same size to enhance the surge capability of their protection scheme.

With IsoMOV™ protectors, designers can now get the right level of surge protection for their application without having to make any performance, size, cost or redesign compromises.
