Introduction of Through Hole Resistors

Through Hole Resistors, also referred to as through-hole mount or THR Resistor, are an important part of an electronic circuit. These resistors are typically supplied to customers in large, thick-walled cylindrical cases with one or two silver-plated wires on each end that are soldered onto a circuit board. The thick-walled casing includes a heat spreading band that helps dissipate maximum heat dissipation.

MFR1WSDRD52-120R Application Field and Working Principle

Specifically, MFR1WSDRD52-120R is a Through Hole Resistor with a Power Rating of 1/2 watt and resistance range of 52-120Ω. As a Through Hole Resistor, MFR1WSDRD52-120R is usually used in high voltage or high precision circuits, as it provides a much higher resistance and voltage rating than other types of resistors. The Principle of Operation is based on the Ohm\'s Law. A resistor connected in a circuit creates an electrical current that is proportional to the voltage across the resistor. This allows the resistor to limit the flow of current through the circuit to decrease the amount of power loss due to resistance of the circuit.The MFR1WSDRD52-120R Through Hole Resistor can be used in a variety of circuits, from simple hobby or DIY projects to more complex professional applications. For example, it can be found in amplifiers, power supplies, and feedback or timing circuits where accurately calculated and maintained resistances are required. In those situations, the MFR1WSDRD52-120R offers excellent performance and is rarely affected by changes in environmental conditions such as humidity or high temperatures.

Attention to MFR1WSDRD52-120R

The MFR1WSDRD52-120R Through Hole Resistor, like all other resistors with power rating over 1/2 watt, should be treated as Class-A, non-heat dissipating components. As the current that runs through them increases, so does the Watts lost due to resistance. This means that when using the MFR1WSDRD52-120R, users should pay particular attention to the power rating, and ensure that it is not exceeding its rated capacity.Another important consideration when using MFR1WSDRD52-120R Through Hole Resistors is the design of the circuit. In order to maximize performance, the resistor should be placed in a manner that ensures maximum airflow across the heat spreader to effectively dissipate heat. It is also recommended that the leads of the resistor be soldered to the circuit board and tightly secured, as vibration or shock can cause the leads to break-off and interfere with the resistor\'s performance.

Conclusion

The MFR1WSDRD52-120R Through Hole Resistor is a reliable and effective high voltage resistor that offers excellent performance in a variety of circuits. Its thick-walled casing helps dissipate heat, and its highly accurate resistance range makes it well suited to high precision and reliable circuit applications. Users should take caution when using the resistor, as exceeding its power rating can result in damage. Users should also pay attention to the placement of the resistor in order to ensure maximum heat dissipation.
