Through Hole Resistors

The CMF5520K500BEEA is a through hole resistor, which is part of a larger class of electrical components known as resistors. Resistors are ubiquitous in electronics and electrical components, coming in varieties such as carbon composition, film, wirewound, or even air-core types. Through hole resistors are named for the fact that they are installed onto the circuit board through two plated through holes. The CMF5520K500BEEA provides a high degree of precision, stability, and low power consumption, and is also relatively small in size. In terms of design, it is setup with two inactive terminals and one active terminal, which can be mounted into the circuit board. a.

Application Field

The CMF5520K500BEEA is primarily used in precision control circuits, such as voltage regulators and related circuits, automatic signal processing, or feedback systems. It\'s small size also makes it well-suited for applications where space is a factor, such as portable devices, and its low power requirements mean that it can be used in low power, battery-operated systems. Due to the presence of the “E” suffix on the part designation, the CMF5520K500BEEA is designed to meet military standards and is, therefore, used in many military grade applications.

Working Principle

The working principle of the through hole resistor is relatively simple. When a current is applied to the resistor, a voltage is developed. Since the voltage developed is directly proportional to the current flowing through it, the resistor can be said to "resist" the passage of current. In the case of the CMF5520K500BEEA, it has a rated resistance of 500 ohms and a tolerance of 5%. This means that, at room temperature, the resistor will have a resistance of between 475 Heath and 525 Heath. It also means that when a current of rated rating is applied, the voltage drop across the resistor will be roughly 0.5 V.

In terms of the two plated through holes, these provide the required physical connection between the resistor and the circuit board. This allows the resistor to be connected to the proper power supply and ground planes on the board and provides the electrical continuity between the resistor and the circuitboard.

Conclusion

The CMF5520K500BEEA is a popular choice in a variety of applications due to its combination of precision, size, and power requirements. It can be seen in many industrial, automotive, and military grade applications for its precise and reliable performance. Its simple working principle involves using the two plated through holes to both physically and electrically connect the resistor to a circuitboard, allowing a specific voltage drop when a rated current is applied.
