The CMF5.51K1700BEEA is particularly suitable for use in power supply circuits, as it offers excellent load regulation, high-impedance stability, low-ripple current, and very low noise levels. It can also be used in analog signal chain circuits for ADCs and DACs, as well as digital circuits where precision timing and accuracy are necessary. Its long-term stability makes it an ideal choice for long-term operation.

Working Principle

The CMF5.51K1700BEEA is a carbon-film resistor, which, compared to wire-wound resistor, has much better tolerance and stability at higher temperatures. A wire wound resistor consists of a fine resistance wire that is wound around a core material. When electricity is applied, the resistance wire heats up, which causes the resistance to increase. This phenomenon is called self-heating and is a major source of inaccuracies in wire-wound resistors.

A carbon-film resistor, such as the CMF5.51K1700BEEA, consists of a thin layer of carbon on an insulating substrate. The resistance of the carbon-film resistor is proportional to the thickness of the film. The substrate material and the carbon layer both contribute to the overall heat dissipation, which reduces the self-heating. This reduces the temperature coefficient of resistance (TCR) and increases the operability and accuracy of the resistor.

The CMF5.51K1700BEEA is also equipped with an internal fusing element, which increases its safety in case of an overload. The fusing element also provides surge protection for the resistor, protecting it from voltage spikes and surges.

Conclusion

The CMF5.51K1700BEEA is an excellent choice for precision applications, offering superior accuracy and stability. The design of the resistor ensures high-impedance stability, low-ripple current, and excellent thermal dissipation, making it an ideal choice for power supply circuits, analog signal chains, and digital circuits. Additionally, the internal fusing element ensures a safe operation in any condition.
