Through Hole Resistors

Through hole resistors are resistors that are installed via exposed leads and wires, which pass through an opening in a circuit board on which the resistor is mounted. This is in contrast to surface mount resistors, which are soldered to the surface of the printed circuit board without the use of exposed wires or leads. Through hole resistors are still widely used in applications where higher wattage ratings, adjustable resistors, or other specialized resistors are needed, as many such components are not available in surface mount packages. This article will discuss the application field and working principle of one such through hole resistor, the MFR-25FRF52-1R5.

Application Field of MFR-25FRF52-1R5

The MFR-25FRF52-1R5 is a through hole resistor designed for superior heat dissipation, wide dynamic range, and long-term stability. These characteristics make it desirable for a variety of high-power, precision applications, from industrial applications such as motor control, instrumentation, and audio amplifiers to commercial applications such as medical imaging equipment, automotive electronics, and RF amplifiers. Its superior heat dissipation allows it to provide power levels up to 25W, making it ideal for these high-power applications. Additionally, its wide-dynamic range and stability make it a great choice for applications requiring a high degree of precision, such as scientific instruments or calibration equipment.

Working Principle of MFR-25FRF52-1R5

The MFR-25FRF52-1R5 has a unique working principle that combines the latest in high-power resistor design with dependable, long-term stability. It is rated at 25W, making it capable of handling high-power applications without the risk of overheating or other issues. Its working principle is as follows:

• At the heart of the resistor is its internal structure, which consists of a large array of rods made of ceramic material. These rods are arranged in a radial pattern, with each rod carrying an electrical current.
• Surrounding the rods is a insulating sleeve made of a heat-resistant material, such as beryllium oxide (BeO). This material helps to contain the heat generated by the resistor, helping to keep temperatures safely below the rated power level.
• Finally, the resistor is enclosed in a metal housing, which helps to protect the internal structure of the resistor from wear and tear.

The MFR-25FRF52-1R5 thus combines the best of high-power, precision resistor design with long-term stability. This makes it a great choice for applications requiring the highest levels of performance and accuracy, such as medical imaging equipment or instrumentation.
