MF72功率型熱敏電阻

1、MF72功率型熱敏電阻1.產(chǎn)品簡(jiǎn)介    為了避免電子電路中在開(kāi)機(jī)的瞬間產(chǎn)生的浪涌電流,在電源電路中串接一個(gè)功率型NTC熱敏電阻,能有效地抑制開(kāi)機(jī)時(shí)的浪涌電流,并且在完成抑制浪涌電流作用以后,由于通過(guò)其電流的持續(xù)作用,功率型NTC熱敏電阻的電阻值將下降到非常小的程度,它消耗的功率可以忽略不計(jì),不會(huì)對(duì)正常的工作電流造成影響,所以,在電源回路中使用功率型NTC熱敏電阻,是抑制開(kāi)機(jī)時(shí)的浪涌,以保證電子設(shè)備免遭破壞的最為簡(jiǎn)便而有效的措施。2.應(yīng)用范圍     適用于轉(zhuǎn)換電源、開(kāi)關(guān)電源、UPS電源、各類電加熱器、電子節(jié)能燈、
