使電子電路免受損害的協(xié)同電路保護(hù)方案(一)

摘要：隨著科學(xué)技術(shù)的發(fā)展，保護(hù)電路元器件己非昔日簡單的玻璃管保險(xiǎn)絲，而是己經(jīng)發(fā)展成為一個(gè)門類繁多的新興電子元器件領(lǐng)域。本文對常用的有關(guān)過電壓保護(hù)和過電流保護(hù)器件的工作原理與特點(diǎn)加以介紹和分析。 敘詞：過電壓保護(hù) 過電流保護(hù) PPTC CPTC MOV TVS GDT Abstract：With the development of science, the circuit protect components has changed greatly, they do not appear as the usual glass tube fuse, the circuit protect components has became an new components fields. Here we will give an instruction and analyze on over-voltage and over-current protect components working principle and properties.
