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瞬间产生的浪涌电流，在电源电路中串接一个功率型NTC热敏电阻器，能有效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非常小的程度，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保证线路的正常工作，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***为简便而有效的措施。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，可靠性高。5.系列全，工作范围宽。.型号Type额定阻值(Ω)RatedResistance稳态电流(A)Max.SteadyStateCurrentDLFDimensions(Unit:mm)DmaxLminF±1Tmaxd5D-5516.5255.0/2.550.55/0.4510D-5100.76.5255.0/2.550.55/0.4520D-5200.56.5255.0/2.550.55/0.455D-7528.5255.050.558D-7818.5255.050.5510D-71018.5255.050.5512D-71218.5255.050.5516D-7160.78.5255.050.5520D-7200.68.5255.050.5522D-7220.68.5255.050.5533D-7330.58.5255.050.553D-93410.5257.5/5.05.50.78/0.554D-94410.5257.5/5.05.50.78/0.555D-95310.5257.5/5.05.50.78/0.556D-96210.5257.5/5.05.50.78/0.558D-97210.5257.5/5.05.50.78/0.5510D-910210.5257.5/5.05.50.78/0.5512D-912110.5257.5/5.05.50.78/0.5516D-916110.5257.5/5.05.50.78/0.5520D-920110.5257.5/5.05.50.78/0.5522D-922110.5257.5/5.05.50.78/0.5530D-930110.5257.5/5.05.50.78/0.5533D-933110.5257.5/5.05.50.78/0.5550D-950110.5257.5/5.05.50.78/0.5560D-9600.810.5257.5/5.05.50.78/0.552.5D-112.5512.5257.5/5.05.50.783D-113512.5257.5/5.05.50.784D-114412.5257.5/5.05.50.785D-115412.5257.5/5.05.50.786D-116312.5257.5/5.05.50.788D-118312.5257.5/5.05.50.7810D-1110312.5257.5/5.05.50.7812D-1112212.5257.5/5.05.50.7816D-1116212.5257.5/5.05.50.7820D-1120212.5257.5/5.05.50.7822D-1122212.5257.5/5.05.50.7830D-11301.512.5257.5/5.05.50.7833D-11331.512.5257.5/5.05.50.781.3D-131.3714.5257.560.781.5D-131.5614.5257.560.783D-133614.5257.560.784D-134514.5257.560.785D-135514.5257.560.786D-136414.5257.560.787D-137414.5257.560.788D-138414.5257.560.7810D-1310414.5257.560.7812D-1312314.5257.560.7815D-1315314.5257.560.7816D-1316314.5257.560.7820D-1320314.5257.560.7830D-13302.514.5257.560.7847D-1347214.5257.560.781.3D-151.3816.5257.560.781.5D-151.5816.5257.560.783D-153716.5257.560.785D-155616.5257.560.786D-156516.5257.560.787D-157516.5257.560.788D-158516.5257.560.7810D-1510516.5257.560.7812D-1512416.5257.560.7815D-1515416.5257.560.7816D-1516416.5257.560.7820D-1520416.5257.560.7830D-1530316.5257.560.7833D-1533316.5257.560.7847D-1547316.5257.560.7850D-1550316.5257.560.780.7D-200.71221.52510/7.571.01.3D-201.3921.52510/7.571.02.2D-202.2821.52510/7.571.02.5D-202.5821.52510/7.571.03D-203821.52510/7.571.05D-205721.52510/7.571.06D-206621.52510/7.571.08D-208621.52510/7.571.010D-2010621.52510/7.571.012D-2012521.52510/7.571.016D-2016521.52510/7.571.03D-253926.52510/7.581.05D-255826.52510/7.581.08D-258726.52510/7.581.010D-2510726.52510/7.581.0)
