CMF5090K900FKEK Through Hole Resistors Application Field and Working Principle

The CMF5090K900FKEK through hole resistor is widely used in electronic circuits for signal, power or protection purposes. It is a device consisting of a resistor element, terminal and enclosure. It can be used in multiple application fields such as control systems, telecommunications, audio and video systems, business machines, automotive industry and robotics. It can be used to limit current, to divide voltages, to adjust circuit impedance, as well as to stablize or protect circuits.The resistor element of a through hole resistor is usually a composition of ceramic and wirewound material. The most common surface mount resistors are metal-oxide film, metal-glaze and wire-wound resistors. The resistors of a through hole resistor are usually made from a metal alloy such as nichrome, nickel alloys, or other similar materials. This prevents the resistor from being destroyed due to excessive electrical current or overloads.A through hole resistor have two electrical properties: resistance and voltage rating. Resistance expresses a value of the amount of opposition an electrical current faces when passing through the resistor. The voltage rating of a resistor expresses the maximum voltage to which a resistor can be exposed before being destroyed.The working principle of the CMF5090K900FKEK through hole resistor is based on the principle of electrical charge’s opposition to flow. A resistor element’s value is expressed in ohms (Ω). The higher the value of a resistor’s ohms, the greater the opposition and resistance it produces to the flow of current. Therefore, a higher value resistor produces a higher resistance towards current flow but a lower value resistor produces a lower resistance towards current flow.The enclosure of a through hole resistor contains a terminal which is used to connect the resistor element’s leads to the circuit board. Generally, three-terminal resistors are used for connection while four-terminal resistors are usually for trimming. Also, through hole resistors are available in different packages such as axial, radial, and surface mount.Ultimately, the CMF5090K900FKEK through hole resistor is reliable, accurate, durable and efficient. It provides protection to a variety of electronic circuits against excessive current and over-voltage and has low power dissipation. It is most commonly used as a signal conditioning device that limits current, adjusts impedance or voltage level, and can be applied to various applications as mentioned above.
