Schurter recently announced its new High Current Fuse (HCF), which it is touting as a robust SMD fuse.
The High Current fuse uses solid-state, thin-film technology. It has fast-reacting breaking capacity rated 1000 A at 125 VAC/ 125 VDC, over a current range of 5 A to 15A. Schurter (Santa Rosa, Calif.) says the HCF is ideal for applications including medical devices, where the reliable interrupt of high currents is critical. In contrast to conventional fuses with a melting wire, the HCF has a metallic thin film layer. With this manufacturing technique, a metal layer is applied in conjunction with a so-called sputter. The two form on a glass substrate in an exact micrometer thickness. The resulting fuse element is enclosed with a ceramic housing, that guarantees the necessary stability and

The Schurter HCF is completely impermeable to potting compound, which can be used to achieve a hermetic seal.
