    压敏电阻是一种限压型保护器件。利用压敏电阻的非线性特性，当过电压出现在压敏电阻的两极间，压敏电阻可以将电压钳位到一个相对固定的电压值，从而实现对后级电路的保护。压敏电阻的主要参数有：压敏电压、通流容量、结电容、响应时间等。
    压敏电阻的响应时间为ns级，比空气放电管快，比TVS管稍慢一些，一般情况下用于电子电路的过电压保护其响应速度可以满足要求。压敏电阻的结电容一般在几百到几千Pf的数量级范围，很多情况下不宜直接应用在高频信号线路的保护中，应用在交流电路的保护中时，因为其结电容较大会增加漏电流，在设计防护电路时需要充分考虑。压敏电阻的通流容量较大，但比气体放电管小。
   压敏电阻的最大特点是当加在它上面的电压低于它的阀值"UN"时，流过它的电流极小，相当于一只关死的阀门，当电压超过UN时，它的阻值变小，这样就使得流过它的电流激增而对其他电路的影响变化不大从而减小过电压对后续敏感电路的影响。利用这一功能，可以抑制电路中经常出现的异常过电压，保护电路免受过电压的损害。
    南京华巨电子是专门生产敏感元器件的，公司生产的片式压敏电阻广泛应用于手机，电脑，MP3等电子产品上，配套厂家有TCL,康佳，中兴通讯，天马微，同舟等IT厂商。并给一些大企业代工贴牌。华巨电子以其过硬的产品质量和强大的研发团队，赢得了同行业的尊重和信赖。贴片压敏电阻由于其体积小，越来越广泛应用于一些手持设备和小型化的电子设备。
