Working Principle of the PR03000202403JAC00 Through Hole Resistor

The PR03000202403JAC00 through hole resistor works by limiting the current flow through the circuit or device. It is composed of a resistor, a heating element and a thermal evaluation element is integrated inside the resistor. When a current flows through the resistor, a self-amplifying heating of the resistor occurs, causing the resistance to increase in magnitude. This also causes the thermal evaluation element to react and increases the temperature further.

The resulting increase in temperature produces a feedback loop, further increasing the temperature. This results in a stabilizing effect on the resistance magnitude and reduces the risk of any sudden changes. As the temperature is reduced, the resistance decreases back to its original state, reducing the current flow through the circuit or device.

Conclusion

The PR03000202403JAC00 through hole resistor is a versatile component used in a wide range of applications such as power supply, voltage regulation - for protecting against over-currents, balancing loads, controlling signal levels, signal shaping and isolation. It works by limiting the current flow through the circuit or device, and its resistance value is self-amplifying in a stable manner. This makes the PR03000202403JAC00 through hole resistor ideal for use in numerous applications.
