Through hole resistors, such as the MFR100FRF52-182K, are widely used in electrical and electronic circuits for purposes ranging from current-shunting, impedance-matching, and as a protection against voltage surge. Many different types are available on the market, including wirewound, cement-filled, and non-inductive resistors. In this article, we will discuss the different applications and working principles of the MFR100FRF52-182K through hole resistor.

The MFR100FRF52-182K is a carbon-fiber, non-inductive resistor designed for use in high power applications. It is designed to withstand high-voltage surges and is capable of dissipating up to 10 watts of power. It has a temperature coefficient of ±100ppm/°C and an operating temperature range of -55°C to +125°C. The MFR100FRF52-182K is typically used in power supplies, static electricity protection, voltage regulation, and feedback circuits.

One application of the MFR100FRF52-182K is in power supplies. It can be used in the power filter section of the supply, as an EMI filter resistor, and as a voltage regulator resistor. The resistor is placed in parallel with the power filter inductor to reduce the voltage ripple common in linear power supplies. The resistor limits the current passing through the circuit when the voltage across the inductor exceeds the maximum limit.

Another application of the MFR100FRF52-182K is as a voltage regulator resistor. A voltage regulator resistor is used to reduce the output voltage of an electronic circuit when the input voltage exceeds a certain level. The resistor is connected in series with the output of the circuit and limits the current passing through the circuit by adding resistance in the path.

The MFR100FRF52-182K can also be used as an EMI filter resistor. An electromagnetic interference (EMI) filter resistor is used in electronic circuits to suppress high-frequency electromagnetic interference (EMI) that could cause interference with other circuits. The resistor\'s value is chosen to add attenuation or filtering of frequencies in the range of the interference.

The MFR100FRF52-182K is also commonly used in feedback circuits. In this application, the resistor is used to provide feedback to an active device like an amplifier or oscillator. The resistor is placed in parallel with the output of the active device, and its value determines the amount of feedback current that passes through the circuit.

The working principle of the MFR100FRF52-182K through hole resistor is based on the basic principle of electrical resistance. When a voltage is applied to the resistor, a current passes through it as dictated by Ohm’s Law. The resistor converts this electrical energy into heat energy, which is then dissipated through the resistor body or a heat sink.

In conclusion, the MFR100FRF52-182K through hole resistor can be used for a variety of applications including power supplies, voltage regulators, EMI filters, and feedback circuits. Its working principle is based on the basic concept of electrical resistance, where a current passes through the resistor when a voltage is applied. The resistor dissipates the energy by converting it into heat energy, which is then dissipated through the resistor body or a heat sink.
