In terms of construction, the device features a rugged, ceramic-based, through-hole design which offers superior thermal performance and reliability. It also has a high-temperature tolerant design that is capable of withstanding temperatures up to 150 degrees Celsius while maintaining its performance.

Working Principle

The working principle of this device can be explained by the following schematic:

The circuit consists of two separate circuits, an input and an output. The input comprises a voltage source, two resistors, two capacitors and a diode. The input is used to provide the power to the device. The output of the circuits has two parts, the feedback circuit and the output resistance circuit.

The feedback circuit consists of a resistor and a capacitor. The voltage from the output of the input is applied to the resistor and the diode in the feedback circuit. The resistor controls the flow of current and the capacitor stores electrical energy. The output resistance circuit consists of two resistors and four capacitors. The output resistance of the device is determined by the four capacitors. The two resistors and four capacitors form a resonance circuit, which allows the device to achieve high power rating and high temperature stability.

The working principle of the CMF651M2100FKR6 is based on the principle of resistive thermal management. The device dissipates energy created by voltage differences through the generation of heat. The heat generated is then dissipated via the output resistance of the device. The feedback circuit and the output resistance circuit work together to control the amount of heat dissipated.
