CMF55178K00FKBF

Through hole resistors are resistors that are mounted to a printed circuit board via a hole drilled in the board, with the appropriate lead wires or terminals inserted into each end of the hole. The CMF55178K00FKBF is a metallic film resistor of this type, specifically designed for use in high-reliability applications such as aerospace, telecommunications and medical technology. As it is slightly larger than standard through-hole resistors, it’s considered one of the “ultra-tiny” types. Its package size is 0402, with dimensions of 1 x 0.5 mm

The CMF55178K00FKBF series is designed to offer improved temperature stability, high power ratings, and accuracy across a wide range of operating temperatures. It is available in E24 and E48 resistance values from 2.2 to 10MΩ with a tolerance of 0.5%, 1%. The temperature coefficient is 100ppm/°C and the power rating is 0.25W.

The resistor is suitable for a variety of applications, including high temperature, high voltage, and high frequency applications up to 5GHz. It can also be used in high-current circuits requiring increased resistance stability with temperature variation. The resistor can be used in automotive and industrial circuits, where its high temperature stability and reliability make it an ideal choice.

The working principle of the resistor is simple. When electrical current flows through the resistor, a portion of that current will be converted to heat energy. This heat energy is then dissipated from the resistor, allowing it to maintain a steady resistance within specified parameters. The resistor is designed to limit the current flow in the circuit by providing a drop across its terminals. This drop is proportional to the amount of current flowing through the resistor and is directly proportional to the resistance of the resistor. By varying the resistance, the current flow in the circuit can be controlled.

The CMF55178K00FKBF resistor is a high-performance, reliable component, offering superior reliability over other standard resistors. With its small size and improved temperature stability, it’s ideal for applications requiring tight tolerances and high reliability in high-temperature environments. It is an excellent choice for use in high-reliability applications such as aerospace, telecommunications and medical applications.
