MALVERN, Pa. — Aug. 18, 2021 — Vishay Intertechnology, Inc. (NYSE: VSH) today introduced a new very fast-acting thin film chip fuse. 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 today will be used in electric (EV) and hybrid electric (HEV) vehicles, where it will provide protection for 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 an outstanding stability of fusing characteristics.

Offering a robust design, the MFU 0603 AT consists of a homogenous 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 in accordance with ASTM B 809, and withstands 85 °C / 85 % R.H. for 1,000 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, 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.

Samples and production quantities of the MFU 0603-FF AT are available now, with lead times of 10 to 14 weeks.
