Through Hole Resistors have come a long way since their inception and the CMF55166R66BEEB model is one of the many examples of the advances seen in the technology. This resistor covers a wide range of applications from signal conditioning, power management, audio-rate signal processing, to line isolation and decoupling. It does this all while fitting into an exceptionally small package, allowing it to occupy minimal PCB real estate.

Description

The CMF55166R66BEEB resistor is a high power, through hole mount, non-magnetic, and low-inductance component. It is mainly used for power support in sensitive applications, such as RF electronics, analog filters, and communications systems. The component is provided in the usual case size of 0606 (0.6" x 0.6") but comes with exceptional power handling capabilities. The component is capable of handling 1W at 1GHz, and has a rated resistance of 660R in ±2%, ±5% tolerances. The device is also rated for an input current of 3A, making it a suitable choice for high-load applications.

Applications

The CMF55166R66BEEB is suitable for a range of applications, particularly in the audio-rate signal processing and line isolation fields. These include radio communication, medical monitoring instruments, power conversion, and communications systems. It is also suitable for mixed signal designs with moderate load, such as RF feedback systems and power management circuits. This resistor is also a reliable choice in EMC protection and in military and aerospace equipment where precision is required.

Working Principle

The CMF55166R66BEEB resistor works on the principle of resistive heating. When a current passes through a resistor, the electrical energy is converted to heat, and some of this heat is lost to the surroundings. The amount of heat dissipated is proportional to the magnitude of the current, and is known as the Joule heating effect. This effect is utilized in the CMF55166R66BEEB resistor to provide power support for analog signal processing. The resistor works by absorbing heat generated by the current and dissipating it to the surroundings with the help of a heat sink. This helps to draw the heat away from the resistor to prevent over heating and damage to other components on the circuit board.

Conclusion

The CMF55166R66BEEB is a Through Hole Resistor which packs a tremendous amount of power into a small package. This makes it an ideal choice for high-load applications, such as RF electronics, medical instrumentation, and power conversion. The resistor works on the principle of resistive heating, and the Joule heating effect is used to dissipate heat to keep the chip from overheating.
