MFR-12FRF52-2K74

Introduction to Through Hole Resistors

Before introducing the specifics of the MFR-12FRF-2K74, it’s important to discuss the basics of through hole resistors. Through hole resistors, as the name suggests, are resistors designed for mounted on printed circuit boards by drilling holes in the board and soldering the resistor onto the board. Through hole resistors have been around since the 1950s, and were originally designed as an easier and more reliable alternative to so called “dog-bone” resistors.Today, most through hole resistors are carbon film, metal film, metal oxide, or wire wound, and generally have axial or radial leads for attaching them to printed circuit boards. Through hole resistors are inexpensive and easy to use, making them popular for a variety of applications. They are available in many sizes and shapes, with the most common type being the axial lead type. Through hole resistors can also be combined to form arrays or networks to create a circuit with more complex behavior.

This resistor is made from high-quality materials, which helps ensure excellent reliability and durability in a wide range of applications. The MFR-12FRF52-2K74 features a robust construction that can withstand large temperature fluctuations as well as a high degree of electrical noise.The working principle of the MFR-12FRF52-2K74 is based on the electrical resistance of the materials used to make it. The resistor is constructed out of a semiconductor material, typically zinc oxide, which acts as the electrical conductor and also the “resistance” element. When an electrical current is applied to the resistor, it produces a voltage drop due to the resistance of the materials in the resistor. This voltage drop is then amplified and sent to the audio circuit.The MFR-12FRF52-2K74 is an ideal choice for audio applications because it offers excellent performance and reliability. It’s also relatively inexpensive, making it a cost-effective solution for any audio project. The resistor is easy to use and can be connected to a printed circuit board in just a few steps.
