电路中精密电阻和熔断器的两级保护方案

Twostage Protection Scheme of Precision Resistor and Fuse in Circuit

精密电阻利用其超低阻和高精度的特性,可以作为微小信号波动的侦测。熔断器可以避免较大异常信号对电路的破坏。将精密电阻和熔断器进行组合,两级保护方案可以使电路应用更加安全。

Precision resistor can be used to detect small signal fluctuation by using its ultra-low resistance and high precision characteristics.The fuse can avoid the damage of large abnormal signal to the circuit.By combining the precision resistor and fuse,the two-level protection scheme can make the circuit application safer.
