Vishay Introduces Very Fast-Acting Thin Film Chip Fuse

Vishay Intertechnology has released a new very fast-acting thin film chip fuse.

Vishay For automotive applications, the Vishay Beyschlag MFU 0603 AT is AEC-Q200 qualified and features current ratings from 0.5 A to 5.0 A.

The device released will be used in electric (EV) and hybrid electric (HEV) vehicles, where it will protect voltage sensing circuits in battery management systems, in addition to circuit protection for small loads.

For these applications, the fuse’s highly controlled thin-film manufacturing process guarantees outstanding stability of fusing characteristics.

Offering a robust design, the MFU 0603 AT consists of a homogeneous metal alloy film deposited on a high-grade ceramic substrate, with fuse elements covered by a protective coating designed for electrical, mechanical, and climatic protection.

The device offers advanced sulfur resistance under ASTM B 809, and it withstands 85 °C / 85 % R.H. for 1000 h biased humidity testing and testing for thermal shock.

Offered in the 0603-case size, the fuse features a rated voltage of up to 63 V, a breakdown capacity of 50 A, and an operating temperature range of -55 °C to +125 °C. RoHS-compliant, halogen-free, and Vishay Green, the fuse is suitable for processing on automatic SMD assembly systems and automatic soldering using wave, reflow, or vapor phase.
