Through Hole Resistors are a common component in the world of electrical engineering and design, and one type of resistor in particular that has gained widespread attention and use is the CMF5556K900BER670. This resistor provides a high-performance solution for applications ranging from low noise to large signal throughput. In this article, we will discuss the application fields and working principle of the CMF5556K900BER670 in detail.

Application Field

The CMF5556K900BER670 through hole resistor was designed for high-reliability applications with demanding electrical requirements. It is suitable for a variety of embedded applications in which a high degree of component performance and reliability is required, such as aviation, automotive, and communication systems. Additionally, due to its superior temperature coefficient, it is also ideal for mission-critical applications where temperature stability is essential.

Its wide range of applications can be attributed to its outstanding power-handling capabilities. With a total dissipation rate of up to 15 watts and a maximum surge rating of up to 30 watts, the CMF5556K900BER670 can handle a variety of signal conditions. Furthermore, its high-temperature TCR of ±100 ppm/°C makes it well-suited for both process and environmental control.

In addition to its performance in high-temperature environments, the CMF5556K900BER670 also features a wide resistance range of 5-100 Mohm, making it suitable for a variety of circuit designs. Furthermore, its EIA standard 0402 package provides excellent process compatibility with an easy drop-in replacement.

Working Principle

At the heart of the CMF5556K900BER670 is a metallic resistor element that is formed using a precise electrochemical etching. The resistor element is housed within a non-conductive epoxy-sealed ceramic package, and the ends of the resistor element are connected to two metal leads. When an electrical current is applied to the leads, the resistance of the resistor is equal to the resistance value printed on the component.

When an electrical current is applied to the component, the electricity is converted to thermal energy, which is then dissipated by the ceramic package. This thermal energy, combined with the resistor’s own self-heating, is known as the “self-heating effect”. The resistor’s self-heating phenomenon can be damaging to accuracy if it is not controlled. To reduce the self-heating effect, the CMF5556K900BER670 is designed with a low inductance, minimizing the amount of stored energy and maximizing the energy dissipation capability.

The CMF5556K900BER670 also features a noise-reduction technology known as a noise-free resistor element. This noise-dampening element works in conjunction with the low inductance and ceramic package to reduce noise and thermal effects. The noise-dampening element is designed to absorb excess energy before it enters the ceramic package and reduce its effect on other components.

Conclusion

The CMF5556K900BER670 provides a reliable solution for applications that require high performance and reliable operation. With its wide resistance range, excellent temperature stability, and outstanding noise reduction capabilities, the CMF5556K900BER670 is an ideal choice for a variety of applications in the electronics industry.
