Through hole resistors are an important component for building and reinforcing circuit boards. The CMF2027R000GNRE through hole resistor is part of the popular CMF2020/2025/2027 series that is designed to reduce the amount of time needed to create a robust, high-performance circuit board. Through careful selection of process variables, it is possible to obtain a stable and reliable through hole resistor that is highly resistant to temperature, moisture, and vibration. This article will cover the application field and working principle of the CMF2027R000GNRE through hole resistor.

Application Field

The CMF2027R000GNRE is an unshielded resistor that comes in either a two- or four-terminal configuration. Due to its compact size, high power density, wide temperature range and reliable performance, it is well-suited for applications such as:

• Automotive electronics
• Industrial systems
• Electronic power supplies
• Electronic communications systems
• Consumer electronics
• Medical equipment
• Lighting systems

The large energy efficiency and maximum dissipation power capabilities make the CMF2027R000GNRE ideal for systems requiring power levels up to 2 watts. The CMF2027R000GNRE is a thermally- enhanced resistor with a power rating up to 3.6 W and a temperature coefficient of -25 ppm/°C at 25 °C. Furthermore, its size allows it to be used in a variety of application environments due to its low-profile design.

Working Principle

The CMF2027R000GNRE is a resistor with two electrically independent poles. The resistance is achieved by passing an electrical current through two resistor elements, which are formed by two alternatively placed metal plates that are separated by a thin layer of insulating material and connected together. The electrical resistance of each plate depends on its construction and the dimensions of the insulating material in between the plates.

The CMF2027R000GNRE is constructed with a top and bottom layer of metallised insulating material. The resistor element in between the two plates is formed by the combination of two materials: a top layer of electrically conducting material, usually aluminium; and a bottom layer of electrically insulating material, usually alumina. The electrical current passes through the aluminium, and is then interrupted by the insulating barrier of the bottom layer.

The amount of current interrupted by the resistor is determined by the amount of material used in the construction of the resistor element. In the case of the CMF2027R000GNRE, the overall resistance is redesigned by varying the thickness of the aluminium layer. The combination of these two elements gives the resistor its particular resistance value, usually expressed in ohms.

The CMF2027R000GNRE is designed for a low-profile and highly reliable design. It is an accurate and stable resistor at temperature ranges from -40°C to +125°C. It also features wide tolerance and temperature coefficient options and is characterized by high reliability, low noise, and low-inductance, making the CMF2027R000GNRE an excellent choice for high-volume applications.

The CMF2027R000GNRE is a reliable through hole resistor that is designed to simplify the design of circuits and reduce the build time. Its stable, reliable performance and wide range of capabilities make it an ideal choice for a wide range of applications in electrical, automotive, industrial, and consumer environments. As such, this through hole resistor is an invaluable component for any circuit board design.
