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.

Bourns® IsoMOV™ Series Hybrid Protection Component has been chosen for Passive Product of the Year by Electronic Products.
