It is recommended for circuit designs that require a resistor with high precision and high power dissipation.

Working Principle

The MR3FB50L0 is a type of through-hole resistor, which means it is mounted on a printed circuit board (PCB) and connected to other components with two solder joints. The resistor works by converting electrical energy into heat energy. The metal film resistors, such as the MR3FB50L0, are particularly effective when it comes to dissipating high power levels without affecting the circuit\'s electrical performance due to the low resistance and low temperature coefficient.

The resistor\'s working principle is based on Ohm\'s law, which states that the current passing through a conductor is proportional to the voltage applied to the conductor. The opposition to current flow creates a voltage drop across the resistor, which is proportional to the amount of current that passes through it. The voltage drop is also dependent on the value of the resistor. Thus, the amount of current that passes through a resistor can be determined by measuring the voltage drop across it.

The MR3F50L0 is designed to work even at high power levels as it has a thermo-resistant coating on its body, which ensures that the temperature does not go beyond the highest operational temperature of 135°C. It also has a temperature coefficient that ensures its resistance remains stable, even as the temperature changes. This helps to maintain the stability of the circuit, even at high power levels.

Application Field

The MR3FB50L0 can be used in a variety of electronic applications, such as power supplies, DC-to-DC converters, digital-to-analog converters (DACs), consumer electronics, and other circuits requiring high power dissipation. It is also used in automotive applications due to its low temperature coefficient and its ability to offer stable performance in harsh environments. This makes it an ideal choice for use in engines and engine control units (ECUs). It is also commonly used in battery chargers, as the large power dissipation capability ensures that the battery is charged quickly and safely.

In addition, the MR3FB50L0 is used in medical applications, such as medical imaging systems, pacemakers, and hearing aids. This is due to its wide operating temperature range, precision tolerance values, and high power dissipation capabilities. It is also used in industrial applications, such as industrial robotics, process control, and vibration control, due to its high power rating and its ability to withstand harsh industrial environments.

The MR3FB50L0 Through Hole Resistor is a reliable and cost-effective resistor designed for use in a variety of electronic and industrial applications. It is designed to offer precise and consistent performance in demanding environments, making it the ideal choice for circuit designs requiring high power dissipation and precision.
