Fuse Resistor, and discharging-type surge absorbing device with security mechanism |
摘要 |
A fuse resistor protects a circuit from a surge, an overcurrent from an unexpected connection, or the like. When a continuous overvoltage higher than a predetermined value is applied to the circuit, the heat from a heat-generating resistant film fractures an insulating substrate of the fuse resistor to open the circuit. Changing the minimum current to which the fuse resistor responds, by modifying a cutout or notch on the substrate, makes it possible to use the fuse resistor anywhere in the circuit. A discharging-type surge absorbing element with a security mechanism that includes the fuse resistor can thus provide protection against a surge or a continuous overcurrent that is more than the rated value of the fuse resistor.
