Orange 275V AC Metal Oxide Varistor 20D431K For Surge Plug , Electronic MOV Varistor

Quick Detail:

• Wide voltage range selection - from 14 VRMS to 680 VRMS.This allows easy selection of the correct component for the specific application.

• High energy absorption capability with respect to size ofcomponent.

• Response time of less than 20 ns, clamping the transientthe instant it occurs.

• Low capacitance values, making the varistors suitable forthe protection of digital switching circuitry.

• High body insulation - an ochre coating provides protection up to 2500 V, preventing short circuits to adjacent components or tracks.

• Approved to UL 1449 edition 3  and manufactured using UL approved flame retardant materials.

• Completely non flammable, in accordance with IEC, even under severe loading conditions.

• Non porous lacquer making the varistors safe for use in humid or toxic environments. The lacquer is also resistant to cleaning solvents in accordance with IEC 60068-2-45.

Description:

Varistors provide reliable and economical protection against high voltage transients and surges which may be produced,for example, by lightning, switching or electrical noise on AC or DC power lines. They have the advantage over transient suppressor diodes in as much as they can absorb much higher transient energies and can suppress positive and negative transients.When a transient occurs, the varistor resistance changes from a very high stand-by value to a very low conducting value. The transient is thus absorbed and clamped to a safe level, protecting sensitive circuit components.Varistors are manufactured from a non-homogeneous material, giving a rectifying action at the contact points of two particles. Many series and parallel connections determine the voltage rating and the current capability of the varistor
