It is also used in high-precision analog electronic circuits and other high-power-dissipation circuits.

Working Principle of H85K11DCA

The working principle of H85K11DCA is based on the resistor’s ability to convert electrical energy into thermal energy. The resistor’s body is composed of a conducting material with a high thermal stability, and the resistance value is adjusted by the size and shape of the resistor’s body. When electrical power is applied to the terminals of the resistor, current passes through the resistor, and the electrical energy is converted into thermal energy, in the form of heat. The heat is dissipated into the surrounding environment, and the resistor is protected from over-current conditions. This maintains the constant resistance of the resistor and ensures the stability of the circuit.

In addition, H85K11DCA also features a self-limiting current function. When the current reaches the maximum value, the resistance of the resistor increases sharply to limit the current flow. This function helps to protect the device from thermal damage caused by an excessive current.

Conclusion

H85K11DCA is a Through Hole Resistor oriented towards high power dissipation applications. It has a wide range of applications, from motor control and medical equipment to high precision analog circuits. It works by converting electrical energy into thermal energy, and its self-limiting current function protects it from thermal overloads. These characteristics make H85K11DCA an ideal choice for a wide range of applications.
