| Accu-Guard(R) SMD Thin-Film Fuse ACCU-GUARD(R) TECHNOLOGY The Accu-Guard series of fuses is based on thin-film techniques. This technology provides a level of control on the component electrical and physical characteristics that is generally not possible with standard fuse technologies. This has allowed AVX to offer a series of devices which are designed for modern surface mount circuit boards which require protection.
