产品简介
MF72功率型NTC热敏电阻器是以过渡金属氧化物为主要原料制成的半导体陶瓷元件。属于负温度系数热敏电阻器的范畴。为了避免电子电路中在开机的*产生的浪涌电流，在电源电路中串接一个功率型NTC热敏电阻器，能*地抑制开机时的浪涌电流，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*小的程度，它消耗的功率可以忽略不计，电压几乎均加到后面设备从而*线路的正常工作，所以，在电源回路中使用功率型NTC热敏电阻器，是抑制开机浪涌保护电子设备免遭破坏的*为简便而*的措施。
应用范围
适用于转换电源、开关电源、UPS电源、各类电加热器、电子镇流器、各种电子装置电源电路的保护以及各类显像管、显示器、白炽灯及其它照明灯具的灯丝保护。
特点
1. 体积小，功率大，抑制浪涌电流能力强。
2. 反应速度快。
3. 材料常数（B值）大，残余电阻小。
4. 寿命长，*性高。
5. 系列全，工作范围宽。 .
产品标识说明
注：1、*大稳态电流遇小数时用三位数表示。其余用实际值表示。
2、额定*功率电阻值遇小数或大于是100Ω时用三位表示，其余用两位表示。
