Bourns AVHT Series multilayered varistors are transient suppressors with temperature independent suppression characteristics enabling protection from -55 C to 150 C. PRODUCT TECHNICAL INVENTORY SAMPLES CONTACT SELECTOR LIBRARY AVHT 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.
