MR1421 MRC Wire Wound Power Resistor

Review MRC Wire Wound Power Resistor Ohm

The MRC MR1421 wire wound power resistor is a high-quality electrical component designed for various applications that require precise power dissipation and voltage dropping. This particular model, with the designation 84, is a 2-watt resistor with a resistance value of 100 ohms.

The MRC MR1421 is a wire wound resistor, which means it is made by wrapping a resistance wire around a former or bobbin. This construction technique allows for a high power rating and excellent stability over temperature. The resistor's wire is made of high-purity copper, ensuring a long lifespan and low electrical noise.

The MRC MR1421 is rated for a maximum operating temperature of 125 degrees Celsius, making it suitable for a wide range of applications. It has a tolerance of /- 1%, meaning the actual resistance of the resistor will be within 1% of its rated value. This high accuracy is essential for applications where precise voltage control is required.

The MRC MR1421 is also known for its excellent stability over temperature. Its temperature coefficient of resistance (TCR) is specified at 250 ppm/ C, which means the resistance of the resistor changes by 0.00025% for every degree Celsius change in temperature. This low TCR ensures that the voltage dropped across the resistor remains stable, even in applications with varying temperatures.

The MRC MR1421 is available in a variety of physical sizes and packaging options, including axial lead, radial lead, and surface mount. The 84 designation refers to the specific physical dimensions and lead configuration of this particular resistor. The resistor is also RoHS compliant, meaning it is free from harmful substances that are commonly used in electronics.

In summary, the MRC MR1421 wire wound power resistor is a high-quality, reliable, and accurate electrical component that is suitable for a wide range of applications. Its wire wound construction, high power rating, and low TCR make it an excellent choice for voltage dropping and precise power dissipation.
