Vishay Intertechnology, Inc. has introduced a very fast-acting thin-film chip fuse to protect electric and hybrid electric vehicles (EV/HEV). The Vishay Beyschlag MFU 0603 AT is AEC-Q200 qualified for automotive applications and features current ratings from 0.5 A to 5.0 A.
The MFU 0603 AT chip fuse is designed to protect voltage sensing circuits in battery management systems, in addition to circuit protection for small loads, in EVs and HEVs. “For these applications, the fuse’s highly controlled thin film manufacturing process guarantees an outstanding stability of fusing characteristics,” said Vishay.
The construction of 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 sulfur resistance in accordance with ASTM B 809, and it withstands 85°C /85% R.H. for 1000 hours biased humidity testing and testing for thermal shock.
The chip fuse, packaged in an 0603 case size, 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. The protection device is 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.
