TDK B72220S0400K101 Standard Metal Oxide Varistor (MOV) offers reliable surge protection for electronic circuits with a capacitance of 6.75nF and clamping current up to 20A. The device features a compact ceramic body coated with epoxy resin to provide mechanical strength and environmental protection.
This metal oxide varistor is rated for a maximum AC voltage of 40V, DC voltage of 56V, and supports surge currents up to 2kA with an energy rating of 37J. Its clamping voltage of 135V and varistor voltage of 68V ensure effective voltage suppression, protecting sensitive electronics against transient overvoltages.
The varistor operates reliably across a wide temperature range of -40°C to 85°C, making it suitable for industrial and electronic applications exposed to varying environmental conditions. The solder termination style and 10mm lead pitch facilitate easy integration into bulk mounting assemblies.
TDK's Standard series guarantees compliance with major international standards such as CQC, IEC, CSA, UL, and VDE, ensuring quality and safety for critical industrial, construction, automotive, and consumer electronics use cases. The epoxy-coated ceramic construction and tinned copper wire leads improve durability and longevity in demanding conditions.
Ideal for industrial electronics, power supplies, surge protection modules, and other applications requiring robust transient voltage suppression, this varistor balances high performance with standard dimensions (21.5mm diameter, 25.5mm length, and 5.4mm thickness) for versatile circuit design integration.
Designed for high surge current rating of 2kA with 37J energy rating. Epoxy-coated ceramic body with tinned copper wire leads for durability. Rated clamping voltage of 135V and Varistor voltage of 68V for effective voltage suppression.
Compact dimensions with 21.5mm diameter and 25.5mm length suitable for bulk mounting. Operates reliably from -40°C up to 85°C temperature range. Complies with international standards including CQC, IEC, CSA, UL, and VDE.
Termination style is solder compatible for easy circuit integration. Standard 10mm lead pitch with 2 pin count configuration. Browse our Electronics Components category at EnvMart for more surge protection components from leading brands like TDK.
