Through Hole Resistors and the MFR-12FRF52-22R1

Through hole resistors are the most basic form of resistors available. They are one of the oldest components still in wide use in the modern electronics industry. Through hole resistors, or THRs, are manufactured from semiconductors such as carbon, cermet, film, metal-oxide, and metal-film. They are used in analog and digital circuits to provide both current and voltage limiting; they are also used for signal conditioning, voltage division, and as part of an impedance-matching network.The MFR-12FRF52-22R1 through hole resistor is a commonly used model for general-purpose electronics applications. This THR features a wide range of standard values, from 1 ohm to 22 meg ohms, making it appropriate for low resistance measurement, voltage division, and signal conditioning in modern electronic circuits.The MFR-12FRF52-22R1 is constructed from ceramic material with gold-plated lead frames. It is rated for both high-temperature operation and high-power operation (1/2 watt at +125°C, 2 watts at +85°C). The THR is capable of withstanding voltage surges up to 80V and can dissipate heat effectively with a maximum operating temperature of +125°C. When selecting an ideal THR for a given application, there are several factors to consider, such as power rating, temperature coefficient, tolerance, and temperature range. With the MFR-12FRF52-22R1, the user can expect excellent performance in all of these categories. The unit\'s high power rating of 2 watts at +85°C ensures reliable operation at higher temperatures, while the wide temperature range of -55°C to +125°C ensures compatibility with a wide variety of operating environments. The resistor\'s low temperature coefficient of 0.3%/°C ensures that its resistance will remain relatively constant over a wide temperature range, while its tolerance of ±5% ensures that the resistor will not fluctuate too much from its stated nominal value.The working principle of the MFR-12FRF52-22R1 THR is based on the concept of “Ohm’s Law”, which states that the potential difference across a resistor is equal to the product of its resistance and the current passing through it. In simple terms, the unit constricts the flow of electrical current according to its resistance, which allows designers to limit the current based on the application’s needs. The MFR-12FRF52-22R1 THR is an ideal choice for a variety of general-purpose electronics applications, from low-level circuit protection to signal conditioning and voltage division. Its superior power rating, wide temperature range, low temperature coefficient, and tight tolerance make it an excellent choice for engineers and designers who require reliable performance in their electronics projects.
