光敏电阻LG34系列规格书

NTC---加电瞬间浪涌电流抑制负温度系数热敏电阻产品简介：在有电容器，加热器和马达的电子电路中，在电流接通的瞬间，必将产生一个很大的电流，这种浪涌电流作用的时间虽短，但其峰值却很大。

在转换电源，开关电源，UPS电源中，这种浪涌电流甚至超过工作电流的100倍以上。

因此，必须有效的抑制这种浪涌电流。

功率型NTC热敏电阻器是以过渡金属氧化物为主要原料制造的半导体陶瓷元件，属于负温度系数热敏电阻器范畴，当电流直接加在功率型NTC热敏电阻器上时，其电阻值就会随着电阻体发热而迅速下降。

由于功率型NTC热敏电阻器有一个规定的零功率电阻值，当其串联在电源回路中时，就可以有效地抑制开机浪涌电流，并且在完成抑制浪涌电流作用以后，由于通过其电流的持续作用，功率型NTC热敏电阻器的电阻值将下降到非常小的程度，它消耗的功率可以忽略不计，不会对正常的工作电流造成影响。

所以，在电源回路中使用功率型NTC热敏电阻器，是抑制开机时的浪涌电流，以保护电子设备免遭破坏的最为简便而有效的措施。

应用范围：用于转换电源，开关电源，UPS电源，各类电加热器、电子节能灯，电子镇流器，各种电子装置电源电路的保护以及彩色显像管、白炽灯及其它照明灯具的灯丝保护特点：体积小、功率大。

抑制浪涌电流能力强。
