Through hole resistors are electronic components used to control the flow of current by determining the electrical resistance. The CPCF05220R0KE66 through hole resistor is an NTC thermistor, a type of variable resistor with negative temperature coefficient. This means that as its temperature increases, its resistance decreases.

Application Field of CPCF05220R0KE66

The CPCF05220R0KE66 is mostly used in over-current, over-temperature and over-voltage protection, temperature measurement, humidity detection, lighting and motor control, battery protection, mobile phone chargers, and other electronic devices. Its wide application fields can provide a comprehensive solution for the protection of electronic products.

Working Principle of CPCF05220R0KE66

The CPCF05220R0KE66 works by using the electrical resistance of a material to control the flow of current. When a voltage is applied across the material, current will flow through it and the current is inversely proportional to the resistance. The CPCF05220R0KE66 has a negative temperature coefficient, which means that its resistance decreases as its temperature increases. This property makes it useful for over-current, over-temperature and over-voltage protection in many electronic devices.

When a current is applied to the CPCF05220R0KE66 and the temperature of the thermistor increases, the resistance of the thermistor will decrease. This means that less current is allowed to pass through and the voltage drop across the thermistor will decrease. This decreases the power supplied to the electronic device, which helps protect it from damage in the event of an over-current, over-temperature or over-voltage situation.

The CPCF05220R0KE66 can also be used as a temperature sensor, as its resistance changes with temperature. By measuring the resistance of the thermistor, its temperature can be determined with a high degree of accuracy. This makes it useful for temperature measurement and control in a wide range of electronic devices.

Conclusion

CPCF05220R0KE66 through hole resistors are widely used in over-current, over-temperature and over-voltage protection, temperature measurement, humidity detection, lighting and motor control, battery protection, mobile phone chargers, and other electronic devices. Its working principle is based on the fact that the resistance of the thermistor decreases as its temperature increases. This property makes it an ideal component for temperature measurement and control, as well as protection from over-voltage, over-current and over-temperature situations.
