Product Description

TDK B72220S1300K102 Metal Oxide Varistor is a high-quality component tailored for automotive and industrial electronic surge protection. This through-hole varistor features a 45 V varistor voltage and a nominal capacitance of 9.4 pF, optimized for stable and reliable suppression of transient voltages.

Its coating utilizes flame-retardant epoxy resin conforming to UL 94 V-0, ensuring enhanced safety and durability under demanding conditions. The varistor element is a round shape designed for optimal energy absorption capacity, particularly effective against load dump and jump-start surges encountered in automotive electronics.

Capable of handling a clamping current of 20 A and maximum surge current of 2 kA, this varistor protects sensitive circuitry by absorbing high-energy transients. Its thin and compact form factor of 6.5 mm thickness, 23 mm diameter, and 27.5 mm length facilitates efficient PCB mounting and space-saving design.

The component operates reliably across a broad temperature range from -40°C to 85°C and meets stringent automotive standards including AEC-Q200. Certifications from CSA, VDE, UL, and IEC further verify its industrial compliance and safety.

Packaging is provided as tape and reel, suitable for automated assembly processes in manufacturing environments. High operating temperature rating up to 125 °C peak. Minimized leakage current ensuring stable protection level.

Terminals constructed from tinned wire improve solderability and electrical connectivity. Robust against cyclic temperature stress for long-term reliability. PSpice simulation models available for circuit design validation.

This metal oxide varistor serves critical roles in automotive electronics, industrial power supplies, and surge protection systems, enhancing device longevity and operational safety.
