电机热保护PTC热敏电阻

Polymer PTC Motor thermal protection. 表面贴装聚合物 PTC (正温度系数) Motor thermal protection using a conductive polymer polymer composite material as a main material. Different from the traditional ceramic PTC Motor thermal protection, 采用易于安装的表面贴装形式，安装方便; A polymer conductive composite material layer with a positive temperature coefficient of resistance effect is used as the core material of the polymer PTC Motor thermal protection. The cost of the product is lower than the ceramic PTC Motor thermal protection, which is more convenient to process and more suitable for the requirements of miniaturized devices.

特征
PTC线性正温度系数热敏电阻采用PTC材料和物理工艺制成. It has excellent stability, complex linearity, repeated millions of times, the characteristic curve is unchanged. 电阻值随温度升高而增大, and changes linearly with good linearity. Compared with PTC polymer ceramic thermistors, the linearity is better, and no linear compensation measures are needed to simplify the circuit design. And the resistance value is consistent, the interchangeability is strong, the shape and specifications are guaranteed. High temperature sensing speed, 1-2 空气介质中秒数, high sensitivity. 小尺寸, sturdy structure, standardized appearance, suitable for automatic installation of printed circuit boards.

■ Application
It is widely used in temperature control, temperature measurement, and temperature compensation in industries such as communications, 汽车, 米, 电脑, and home appliances. The universal PTC positive temperature thermistor's resistance temperature characteristic is abrupt, and the linear region is very narrow. Usually used for circuit overcurrent protection, not for temperature detection, temperature compensation circuit. This product complements this area of application.

我公司生产的线性热敏电阻分为两个系列. 一是单晶硅线性PTC热敏电阻SCKTY系列, 其特点是温度系数大，每度7000PPM, 可替代NXP的KTY系列热敏电阻和RTI的DS系列.
