Frequently Asked Questions

What is the difference between TMOV and TFMOV?

TMOV integrates a thermal fuse directly with the varistor in a single package. TFMOV is a discrete combination of a thermal fuse and MOV connected in series, often with additional features like remote signaling.

Are your products certified?

Yes, our TMOV and TFMOV products are certified by UL, TUV, and CQC. We also comply with ISO 9001 and IATF 16949 quality standards.

Can I request custom specifications?

Yes, we support OEM/ODM projects and can customize voltage ratings, packaging, and performance parameters based on your design needs.
