Through hole resistors are one of the most popular types of resistors used today. The CMF5527K000FKRE is a miniature through hole resistor with high power rating, low series resistance, extended life, and superior temperature stability. It is suitable for use in a wide range of applications in the industrial, instrumentation, automotive, aerospace, and medical industries. This article will discuss the application field and working principle of this type of resistor.

Application Field

The CMF5527K000FKRE is designed with a low high voltage tolerance, making it suitable for use in applications where discontinuous conduction mode (DCM) is essential for greater reliability. This makes it ideal for noise filtering, audio mixing, and PWM/bang-bang applications. It is also commonly used in medical applications such as electrocardiograms (ECGs), electroencephalograms (EEGs), pulse oximetry, and other biological/physiological measurements. Additionally, this resistor is used in critical automotive applications such as motor control, engine control systems, and other applications requiring high accuracy and reliability.

In industrial applications, the CMF5527K000FKRE is suitable for applications requiring a low mounting/insertion impedance and a high-voltage tolerance. This type of resistor can also be used to increase system reliability in environments where high temperatures or humidity is an issue. It is also suitable for applications where noise is an issue, such as power supplies and semiconductor devices.

Working Principle

The working principle of the CMF5527K000FKRE is based on Ohm\'s law, which states that the current passing through a resistor is directly proportional to the voltage across it. This type of resistor works as a resistor when placed in a circuit, providing a precise impedance to the applied voltage. When a current is applied, the resistor’s resistance limits the current flow and dissipates some of the energy in the form of heat.

The CMF5527K000FKRE also works on the principle of self-regulation. This means that the resistor will adjust its size and operating characteristics to match the applied voltage. This is done by using a self-regulating resistor material, which has the ability to change its resistive value with temperature. This allows the resistor to increase its resistance with increasing temperature, while also maintaining a stable voltage. This ensures a reliable and consistent output over a wide temperature range.

The CMF5527K000FKRE is also designed to operate at high frequencies. The high-frequency capability ensures that it can be used in applications that require signals with high frequencies, such as RF (radio frequency) communications and other high-speed systems.

Overall, the CMF5527K000FKRE is an excellent choice for a wide variety of applications. It has a high power rating, low series resistance, extended life, and superior temperature stability. Its ability to self-regulate and operate at high frequencies makes it suitable for applications where noise is an issue, high accuracy is required, and reliable performance is essential.
