NTC热敏电阻

超大功率NTC热敏电阻

查看次数:2594
产品描述:

NTC(负温度系数)热敏电阻是一种热敏性半导体电阻器,其电阻值随着温度的升高而下降,电阻温度系数在-2%/k~-6%/k范围内,约为金属电阻温度系数的10倍。NTC热敏电阻器电阻值的变化可以由外部环境温度的变化引起,也可以因有电流流过,自身发热而造成。他的各种用途都是基于这种特性。NTC热敏电阻器由混合氧化物的多晶陶瓷构成。这种材料的导电机理是相当复杂的。

超大功率NTC热敏电阻是华巨电子采用特殊工业和特殊构造生产的NTC功率型热敏电阻,本系列热敏电阻具有大稳态电流,大阻值,本身能够承受大功率消耗的NTC热敏电阻。广泛应用于各种大功率UPS电源,逆变电源等高功率电子电气设备
