产品介绍
温度保险丝是一种不可复位型热敏保护器件，用于家用电器及工业设备的过热保护，当周围温度升高到某不正常温度时，温度保险丝感受外界温度状态，将电路切断。它的全密封结构确保其熔断系统稳定可靠，不受外界潮湿等恶劣环境影响。它的主要特点是：对外界温度感受灵敏；动作温度准确、稳定；体积小，密封式结构；性能可靠，已获多个国际安全标准认证。

参数说明
* 额定动作温度 Rated functioning temperature ( Tf)
温度保险丝按安全标准规定方法测试，改变其导电状态的温度。按基于IEC691的安规标准规定，
温度保险丝必须在上述温度+0/-10℃范围内动作。简称Tf.
* 实际动作温度 Fusing-off temperature
温度保险丝在硅油池内以每分钟0.5 -1.0℃速率升温，检测电流小于10mA条件下所测得的
熔断温度。它是温度保险丝的实际动作温度。
* 保持温度 Holding temperature ( Th )
温度保险丝在通过额定电流时，能保持168小时而不会改变其导电状态的最高温度。用Th表示。
* 极限温度 Maximum temperature limit ( Tm )
温度保险丝能承受10分钟而不会发生重新接通现象的最高温度。简称为Tm.
* 额定电流 Rated current ( Ir )
温度保险丝所能承载的最大电流。
* 额定电压Rated voltage ( Ur )
温度保险丝最高工作电压.
