Through-Hole Resistors, such as the CMF072R7000GNR6, are components used to provide a specific resistance value, controlling current flow in an electronic circuit. They are also used to create voltage distributions in a circuit, provide heat dissipation to components, and reduce electrical noise. The exact usage of Through-Hole Resistors depends on their design and application field.

The CMF072R7000GNR6 is a precision bandpass Through-Hole Resistor designed for medium power applications. It is made with a ceramic substrate and a thin film of metal alloy. It has maximum voltage and current of 1250V and 4A, respectively. In addition, it features low temperature coefficient of resistance (TCR) of 0.1ppm/K, high load life stability of 0.2ppm, and low signal-to-noise ratio (SNR) of 70dB.

When used in circuit boards, the CMF072R7000GNR6 provides an exact resistance value. It is designed to resist changes in temperature and humidity, which makes it suitable for applications requiring temperature-compensated circuits. For example, it is used in automotive systems, medical labs, and industrial automation, where precision is paramount.

The working principle of the CMF072R7000GNR6 is based on its design. The metal alloy thin film acts as a resistor and is composed of two layers: a connected metal layer which provides current flow and a semi-conductive layer which provides the resistance. As current flows through the connected metal layer, it generates heat, which is dissipated through the semi-conductive layer. This helps maintain a constant resistance despite changes in temperature or humidity.

In addition to providing the desired resistance, the CMF072R7000GNR6 also offers protection to the circuit. When a short circuit occurs, the resistor will blow, preventing further damage to the components in the circuit. This is because the resistor has a higher resistance value than the rest of the circuit, and when the current reaches its limit, it will break or blow the resistor.

The CMF072R7000GNR6 is a highly reliable Through-Hole Resistor designed for precision applications in automotive, medical, and industrial automation circuits. It offers a precise resistance value and ensures an even current flow while providing protection from short circuits. With its low TCR and high load life stability, the CMF072R7000GNR6 is an ideal choice for circuits requiring precise and reliable performance.
