CMF554K2200BEEA Datasheet/PDFThrough Hole Resistors
A through hole resistor (also known as a leaded resistor) is an electronic component which provides resistance to electrical current flow. This type of resistor has two leads (or lugs) that protrude from its body and are inserted into corresponding holes in the circuit board. It is typically used in applications that require higher voltage ratings or more robust construction than surface mount resistors.
The CMF554K2200BEEA is an example of a through hole resistor. It is a fixed carbon film resistor rated at 2.2kOhms with 10% tolerance. It has a maximum power rating of 1/2W and a maximum operating temperature of +250°C.
The general application of the CMF554K2200BEEA is to provide the necessary resistance to protect the circuit’s active components. For example, the resistor can be used to limit the amount of current passing through a transistor or to decrease the voltage level in a signal line. Other applications include providing currents that can be used to activate a buzzer or indicator light. In addition, as the component has a high tolerance rating it is suitable for use in applications which require high accuracy such as precision measurements.
The working principle of a through hole resistor is based on Ohm’s law, which states that the current through a conductor between two points is directly proportional to the voltage applied across the two points. This can be expressed mathematically as I = V/R, where I is the current, V is the voltage, and R is the resistance.
The resistance of the CMF554K2200BEEA is determined by the material it is made from and the geometry of its leads. The material for this resistor is a type of carbon film that has been tested to prove it is suitable for long-term stability. The geometry of the leads are such that when inserted into a standard circuit board hole, the heat generated by the current flow is effectively dissipated.
In conclusion, the CMF554K2200BEEA is a through hole resistor with a rated value of 2.2kOhms and a 10% tolerance. It is designed for general applications such as current limiting and voltage level adjustment. The component is based on Ohm’s law, with the resistor’s resistance being determined by not only the material it is made of, but also the geometry of its leads.
