Bourns AV Varistor 4.5 nF 5 A Clamping 40 V Varistor 24 V Surface Mount 1812 AV14K1812801NIR1

Bourns AV14K1812801NIR1 AV Series varistor is a high-performance surface mount component designed for transient voltage suppression in electronic circuits.

This varistor features a capacitance of 4.5 nF, a clamping current of 5 A, and a clamping voltage of 40 V, making it suitable for precise voltage regulation and transient energy absorption.

The device operates over a wide temperature range from -55°C to 125°C and is housed in a compact 1812 package with dimensions 4.7 mm length, 1.3 mm thickness, and 1.3 mm depth, ideal for space-constrained PCB layouts.

The maximum rated AC voltage is 14 V, and DC voltage is 16 V with a surge current capacity of 2 kA, supporting resilience against voltage spikes. Its energy rating of 0.3 Joules allows it to absorb moderate transient energy during surges.

Manufactured with a non-plastic coating, this varistor delivers better flammability ratings compared to typical silicon TVS diodes, offering safer operation in demanding industrial and electronic applications.

The component is RoHS compliant, ensuring environmentally friendly manufacturing standards, and is supplied in tape and reel format to facilitate automated assembly lines.

Typical uses include surge protection in industrial power supplies, electronic control units, consumer electronics, and other applications requiring reliable transient voltage suppression.

Clamping voltage assures protection of sensitive circuit elements. Compact form factor optimizes PCB space. Wide operating temperature range supports diverse environments. RoHS compliant for environmental and regulatory standards.

Suitable for transient energy distribution in high-reliability systems. Explore more Bourns electronics components and Varistors for high-quality surge protection solutions on EnvMart.
