How do you know that the thermistor is broken? The multimeter selects the appropriate resistance gear. The two test leads are respectively contacted at both ends of the thermistor, and the thermistor is heated by hand or heated by other mea....
Thermistors are sensitive components that are developed early, have many types, and are more mature. The thermistor is composed of a semiconducting ceramic material, and the principle of utilization is temperature-induced resistance change.....
NTC (Negative Temperature Coeff1Cient) is a thermistor phenomenon and material with a negative temperature coefficient that decreases exponentially with increasing temperature. The material is a semiconductor ceramic obtained by sufficientl....
The electronic temperature controller not only has the same temperature characteristics as the pressure type thermostat, but also can easily change the temperature characteristics according to the requirements of the refrigerator manufactur....
The TC4011BP (Q801) is connected to two RS flip-flops. Among them, RS1 is used to control the operation of the compressor, and RS2 is used to control the defrosting work. The working process is as follows: When the RS11 pin is low, 3 feet a....
Portable electronics are growing rapidly. From cell phones and MP3 players to PDAs, personal DVD players and more traditional laptops. People began to revisit many aspects of consumer and professional product design. This change is most evi....
Resettable fuses for battery protection a, Cell phone battery pack: The key to the cell phone battery pack is its application characteristics. This battery is housed in a small, light and narrow box. NICD, NiMH, Li-ION, these three main che....
PTC Thermistor Application Protection Ballast Fluorescent lamps require a ballast that generates high voltage and current to light. The ballast controls the electrical characteristics of the fluorescent lamp. When the lamp is turned on, the....
14, Vmax maximum voltage (withstand voltage value) Under the limited conditions, the resettable fuse series polymer PTC thermistor can safely withstand the highest voltage when it operates. That is the withstand voltage value of the thermis....
1.Rated zero power resistance The PPTC thermistor should be packed according to the zero-power resistance, and the resistance value range should be marked on the outer packaging. After the withstand voltage and current resistance test, the....
