MFR2WSFTF52-1K58

Through-hole resistors have been used throughout the industry for more than a century, and the MFR2WSFTF52-1K58 is one such example. This resistor is a metal film resistor with a 2 watt power rating, and it contains a metal film resistor element and a metal oxide coating deposited over the resistor. The coating serves to provide electrical insulation, protect against vibration, and improve overall reliability. In addition to these features, the resistor has a 1 kOhm resistance value. This value ensures that no more than 1 watt of power is dissipated in the resistor.

The MFR2WSFTF52-1K58 has a wide range of applications, primarily in the industrial, automotive, and telecommunications fields. The resistor can be used as a voltage divider in industrial process control systems, as a current limiter in automotive electronic systems, and as an amplifier termination in telecommunications systems. As the applications suggest, the resistor is designed primarily for DC applications, as its power rating is too low for AC applications. However, by using multiple resistors in parallel, the power rating can be increased.

The working principle of the MFR2WSFTF52-1K58 is quite simple. When a voltage is applied to the two terminals of the resistor, a current will flow due to the resistance of the resistor. This current will be proportional to the applied voltage, up to the power rating of the resistor. Beyond the power rating, additional voltage will cause the resistor to overheat, and the current will be limited by the temperature protection devices built into the resistor. The resistor will then dissipate the excess energy as heat and reduce the current.

Overall, the MFR2WSFTF52-1K58 is a reliable and versatile resistor, suitable for a wide range of industrial, automotive, and telecommunications applications. With its 2 watt power rating and 1 kOhm resistance value, the resistor provides a good balance between power dissipation and electrical insulation, ensuring that it can be used safely in a variety of settings. Its simple working principle also makes it easy to use and maintain.
