Through hole resistors are a type of resistor that can be affixed directly to a circuit board using its two metal terminals that are inserted directly into pre-drilled holes. The metal terminals themselves each have a chemical coating, called a soldermask, that completely insulates them from one another and from the target circuit board.

MFR-12DRD52-2K21 is one of these resistors, which is designed to provide a precise, definite resistance value with negligible power dissipation. It’s two metal terminals allow it to be easily connected to a circuit board and they are designed to draw current away from the sensitive IC devices, such as in power supplies, audio amplifiers and video amplifiers. MFR-12DRD52-2K21 has a brief lead-out time and is primarily used in low-voltage applications, where cost reduction and high reliability is essential.

MFR-12DRD52-2K21 consists of an annealed, non-corroded, stainless steel frame, which houses the resistor and two copper-plated steel terminals for connection. It has an impressive resistance value rating of 2 kilohms and offers an accuracy of ± 5%. It also has a good temperature coefficient of resistance which allows it to maintain its values well even at temperatures extremes. It is capable of withstanding high voltages, making it suitable for use in a wide variety of applications including LED displays, consumer electronics, and automotive sound systems.

The working principle of the MFR-12DRD52-2K21 through hole resistor can be explained by the fact that the resistor has two parts, the first part being an annealed, non-corroded, stainless steel frame. The second part is a funnel-shaped armature, which houses the resistor. This armature is made up of several layers of ceramic-core core that are finely insulated with a high-performance dielectric material, such as Barium titanate. The armature is then filled with an electrolyte, which helps the resistor to maintain the same resistance value at all times.

This resistor is often used in conjunction with other components such as amplifiers and filters, as its low noise level allows it to maintain signal integrity and minimize distortion. It is ideal for signal conditioning in RF and optical systems, signal samplers, and embedded systems. Additionally, its low heat dissipation ensures reliable operation under all conditions. It is also suitable for usage in high-voltage, high-current and high-frequency applications.

The MFR-12DRD52-2K21 through hole resistor is an excellent choice for low-voltage applications, where the cost-reduction and high reliability is an essential requirement. It is capable of withstanding high voltages, making it suitable for a wide variety of applications. Its Low noise level and good temperature coefficient of resistance allow it to retain its value under extreme temperatures making it useful for signal conditioning, RF and optical systems, signal samplers, and embedded systems.
