Product Description

TDK B72660M0301K072 is a metal oxide varistor (MOV) designed for surface mounting applications that require effective transient voltage suppression. This CU series varistor features a clamping voltage of 775 V and supports a clamping current of 10 A, providing reliable protection against voltage spikes in electronic circuits.

Encapsulated in thermoplastic meeting UL94 V0 flammability requirements, it ensures enhanced safety and durability while maintaining compact cylindrical form factor with tinned copper terminations for soldering reliability.

With a maximum AC voltage rating of 300 V and a maximum DC voltage rating of 385 V, this varistor is capable of handling high voltage transients. The maximum surge current rating of 1.2kA and an energy rating of 23 joules make it suitable for protecting sensitive electronic equipment from transient surges caused by lightning or switching events.

Compact physical dimensions (length 10.2 mm, height 4.5 mm, depth 8 mm) allow for space-efficient PCB layouts. The device operates reliably up to 105°C ambient temperature, making it well suited for industrial, consumer electronics, and power supply applications.

This Varistor complies with international standards including CQC, VDE, CSA, IEC, and UL, certifying its quality and safety. Although it is not designed for automotive standard compliance, it is ideal for a broad range of electronic and electrical devices requiring transient voltage surge protection.

Encapsulation in UL94 V0 thermoplastic enhances safety and heat resistance. Surface mount cylindrical design fits compact PCB applications. High clamping current of 10 A and voltage of 775 V for robust surge protection. Maximum surge current rating of 1.2kA ensures effective transient suppression.

Energy rating of 23 joules protects electronic circuits from transient damage. Operating temperature up to 105°C supports reliable performance in harsh environments. Certified by CQC, VDE, CSA, IEC, and UL for international safety compliance.

This product is commonly used in industrial, consumer electronics, power supply systems, and electronic circuit protection to minimize malfunction and damage from voltage transients.
