CMF2047K000GNEB Application Field and Working Principle

Through Hole Resistors, or THRs, are a type resistor with two or more leads that are inserted in holes or slots cut into a printed circuit board. The first THRs are believed to have been introduced in the 1960’s, but they remain one of the most widely used resistor types today.

Characteristics

THRs offer many advantages over other types of resistors. They are inexpensive and come in a wide range of values, from several ohms up to several gigaohms. They also have good heat dissipation properties, allowing them to be used in applications that require power dissipation for heat transfer. Additionally, they are highly reliable and durable and can easily be mounted, soldered, or inserted into printed circuit boards to create a solid connection.

CMF2047K000GNEB

The CMF2047K000GNEB is a through-hole resistor suitable for use in sensing circuits and other high voltage applications. It has a high voltage rating of 2kV, making it suitable for use in a wide range of applications, including industrial, automotive, medical, and aerospace circuits. The device has high accuracy and stability, making it suitable for precision applications.

Working Principle

THRs work by providing a resistance to the flow of electrical current. When a voltage is applied across the resistor terminals, current will flow through the resistor. As the current passes through the resistor, it will lose energy, which is dissipated as heat. The amount of resistance the resistor provides is determined by the material from which it is made, as well as the size and shape of the resistor lead.

Applications

THRs are widely used in a variety of applications, including sensing circuits, current limit and impedance matching circuits, power and voltage filtering circuits, and as part of voltage dividers and signal conditioning circuits. In motor control circuits, they are used to sense the current flowing through the motor and to provide precise current limiting. In communications and control circuits, they are used to provide impedance matching and frequency filtering. THRs are also used as light-dependent resistors in light sensors, as variable resistors in potentiometers and trimmers, and as power resistors in various heating and lighting circuits.
