Radial Leaded Ultra Big Power NTC Thermistor MF73 For Switching Power Supply I Description Of The Ultra Big Power NTC Thermistor MF73 High-Power NTC Thermistors are used to reduce the inrush current that occurs when an electrical device is switched on. High inrush current is the result of the maximum instantaneous input current drawn by an electrical device during the initial power up. As technology continues to advance, most systems today run efficiently and maintain a low impedance which in turn contributes to high inrush current. Additionally, devices that produce alternating current such as electric motors or transformers can draw several times their steady state current at switch on. Although this additional draw of inrush often lasts less than ½ of a normal 60 hertz cycle, that is enough time to cause possible damage to the equipment. II Application Of The Ultra Big Power NTC Thermistor MF73 * All kinds of power supply,UPS power supply,Switching power supply * EV charger,charging pile * Motor driver,superpower server motor driver,logic controller * High power plasma electric welder,cutting machine,super power lightning lamp * Nuclear managetic resonance equipment,super power audio power amplifier,high circle transformer * The solar panel arrays with high capacity power inverter * The industrial robot drived by high voltage power supply, intelligent electric cabinet with low voltage.

Inrush Current Limiter Power NTC Thermistor MF72 5D-13 5Ohm 13mm 5A For Power Supply III Description Of Power NTC Thermistor Inrush Current Limiters are used to reduce the inrush current that occurs when an electrical device is switched on. High inrush current is the result of the maximum instantaneous input current drawn by an electrical device during the initial power up. As technology continues to advance, most systems today run efficiently and maintain a low impedance which in turn contributes to high inrush current.

Novel structure, superior performance and high quality 2. High sensitivity and fast response time 3. Good sealing performance, strong adhesion, moisture-proof and anti-corrosion 4. Large-scale production, high cost performance, high quality and low price VI Thermistor Temperature Detection in Fire Alarms The thermistor method, unlike the previous examples, uses heat detection to activate. The alarm activates once the thermistor detects a high temperature. Thermistor temperature detection doesnot require smoke to activate and has fewer false alarms. The thermistor uses the ambient temperature of a building and will only activate when that temperature increases exponentially. The thermistor method is reliable in this fire alarm example as there would be few false alarms and a quicker alert rate, but the thermistor method is also versatile.
