Features Formerly a product Non-plastic coating for better ammability rating Five model sizes available - 0805, 1206, 1210, 1812 and 2220 +125 C maximum continuous operating temperature Supply voltages: 12 V, 24 V and 42 V Load Dump Energy up to 50 J available Broad range of current and energy upon request handling capabilities RoHS compliant* Low clamping voltage - V c AEC-Q200 Grade 1 upon request Non-sensitive to mildly activated uxes AV Series Automotive Grade Varistors General Information Additional Information Almost all electronic systems in an automobile, e.g., anti-lock brake system, direct Click these links for more information: ignition system, airbag control system, wiper motors, etc. are susceptible to damage from destructive voltage transients. Bourns AV Series multilayered varistors are transient suppressors with temperature independent suppression characteristics enabling protection from -55 C to +125 C. PRODUCT TECHNICAL INVENTORY SAMPLES CONTACT SELECTOR LIBRARY AV Series varistors offer excellent transient energy distribution. AV varistors require significantly less space and pad area than silicon TVS diodes, offering greater circuit Multilayered Varistor Symbol board layout flexibility for the designer.
