Each thermistor has parameters such as withstand voltage, withstand current, maintain current and action time. You can choose the parameters of the product according to the requirements of the specific circuit. The specific methods are as fo....
1, rated zero power resistor R25 Zero power resistor. When the PTC thermistor value is measured at a certain temperature, the power consumption added to the PTC thermistor is extremely low, so that the resistance change of the PTC thermisto....
The self-recovering fuse is made of a conductive material added with a conductive material. The basic principle is a balance of energy. When a current flows through a component, heat is generated, and a part of the generated heat is emitted....
PTC refers to the phenomenon of thermistor or raw material with a sharp increase in resistance and positive temperature coefficient at a certain temperature, which can be used as a constant temperature sensor. The raw material thus BaTIO3 or....
1, resistance-temperature characteristics Although there is a slight difference between the normal temperature and the Curie point temperature, POSISTOR still shows almost constant resistance-temperature characteristics. Its resistance-temp....
The PTC heating element is also called a PTC heater, and is composed of a PTC ceramic heating element and an aluminum tube. This type of PTC heating element has the advantages of small thermal resistance and high heat exchange efficiency, an....
Most of the existing heaters are heated by conventional devices such as electric heating tubes and electric heating wires. The outer casing of the electric heating pipe is a steel pipe made of stainless steel, and has a heating element resis....
1. Scope of application: The WMZ12A PTC thermistor is mainly used for overcurrent protection of [transformer (adapter) / primary coil / charger / digital multimeter / smart meter / micro motor / transistor]. Directly connected in series in....
WMZ12A (II) is mainly used for lightning protection, communication machine over-current protection Other electrical performance parameters: Power frequency resistance: 3Arms 220Vrms 20TImes Lightning strike resistance: 10/310s 1.5KV37.5A 10....
1. Scope of application: WMZ11A PTC thermistor is used in various fluorescent electronic ballasts and electronic energy-saving lamps without changing the wiring. The appropriate thermistor can be directly connected across the resonant capac....
