Vishay Intertechnology Adds Three Devices to MFU Series

Vishay Intertechnology Inc. (Malvern, PA) announced the release of three new devices in the MFU Series of thin-film, flat chip fuses that offer quick-acting fuse characteristics with rated current values up to 5.0 A, as well as stability verified in accordance with UL 248-14 and IEC 60127-4. The Vishay Beyschlag MFU 0603 and MFU 0805 devices are rated for a current range of 0.5 A to 4 A. However, the MFU 1206 devices feature rated current values up to 5.0 A. Rated voltage is 32 V for the MFU 0603 and MFU 0805, and 63 V for the MFU 1206. At these rated voltages, the devices provide a breaking capacity of 50 A.

The new MFU 0603, MFU 0805, and MFU 1206 are designed to provide secondary over-current protection for power inverters, motion-control units, dc-dc converters, battery chargers, and low-voltage power supplies in information technology, telecommunications, automotive, medical, and audio and video systems. Available in standard metric case sizes - RR 1608M (1.55 mm x 0.85 mm x 0.45 mm) for the 0603 chip fuse, RR 2012M (2.0 mm x 1.25 mm x 0.45 mm) for the 0805 chip fuse, and RR 3216M (3.2 mm x 1.6 mm x 0.55 mm) for the 1206 chip fuse - the thin-film flat chip devices integrate easily into a broad range of end products.

The MFU 0603, MFU 0805, and MFU 1206 support lead-free soldering and are suitable for processing on automatic SMD assembly systems using wave, reflow, or vapor phase processes. The terminations for the lead-free MFU chip fuses are pure tin-on-nickel plating. The immunity of the plating against tin whisker growth has been proven under extensive testing. All products comply with the CEFIC-EECA-EICTA list of legal restrictions on hazardous substances. Samples and production quantities of the new chip fuses are available now, with a lead time of 8 to 10 weeks for larger orders. Pricing for US delivery in small 5,000-piece quantities ranges from $0.17 to $0.37 per piece, depending on size and value of the rated current.
