MF72 power NTC thermistor inrush current limiting

MF72 NTC thermistor for chargers

MF72 NTC thermistors are commonly used in chargers to protect against overcurrent and overvoltage conditions. These thermistors are placed in series with the charging circuit and have a negative temperature coefficient which causes their resistance to decrease as their temperature increases. This property allows the thermistor to act as a self-resetting fuse, limiting the current to a safe level as the temperature of the device increases.

Additionally, MF72 power NTC thermistor can be used to provide temperature compensation for charging circuits. As the temperature of the charging circuit changes, the resistance of the thermistor changes, allowing the charging circuit to maintain a constant output voltage. This is important for preventing damage to the charging device and ensuring efficient charging of the battery.

Overall, the use of MF72 NTC thermistors in chargers is important for ensuring the safe and efficient operation of these devices.
