Fuses covered by this specification are intended for use in electronic and low power electrical equipment where relatively low values of short circuit currents are encountered. The fuse primarily provides protection and isolation for the equipment itself. These fuses are designed to endure environmental requirements not specified in MIL-PRF-15160. The fuses covered by this specification are unique due to the fact that these devices must be able to operate satisfactorily under the following demanding conditions: 10 g's vibration, 100 g's of shock, thermal shock from −65°C to +125°C and 48 hours of salt atmosphere. In addition, these requirements are verified under a qualification system. Commercial components are not designed to withstand these environmental conditions.
