Bourns, AVHT Varistor 4.5nF 5A, Clamping 40V, Varistor 24V, 1812 (4532M)

The Bourns AVHT series auto SMD varistors are transient suppressors with temperature independent suppression characteristics enabling protection from -55 °C to 150 °C operating temperature ranges which offers prevention to almost all electronic systems in an automobile, e.g., anti-lock brake system, direct ignition system, etc. to get damage from destructive voltage transients. Five model sizes available offers broad range of current and energy handling capabilities and also offer excellent transient energy distribution.

AVHT series varistors require significantly less space and pad area than silicon TVS diodes
+150 °C maximum continuous operating temperature
Low clamping voltage Vc
RoHS compliant
Non-sensitive to mildly activated fluxes
Non-plastic coating for better flammability rating
