Through Hole Resistors, such as the MFR-25FRF52-402K, are resistive components which control, limit or provide current in a circuit. These resistors are composed of a cylindrical helix of a non-conductive material, which is wound around a cylindrical core and soldered to a terminal. In some cases, the same non-conductive material may be used for both the central core and the helix.

The MFR-25FRF52-402K is a through hole resistor built to the MIL-STD-202 standards, and is designed to dissipate a maximum of 0.2 watts of power. Its resistance value is measured at 402K ohms (+/- 5%), which is suitable for use in low to medium voltage applications. It is constructed from copper-clad laminates, which give it superior strength and durability. It is also designed to have a very low insertion loss, meaning that less current is lost as it passes through the resistor itself.

The MFR-25FRF52-402K is most commonly used in applications such as circuit protection, signal conditioning, and voltage reduction. It is particularly useful for circuits where a high resistance value is needed, such as filtering circuits or sensor feedback control. It can also be used as a shunt for current protection, to limit the amount of current passing through a given circuit.

The MFR-25FRF52-402K is designed to use a two-terminal structure, with one of the terminals connected to the resistor itself and the other connected to the surrounding circuit. This two-terminal structure ensures that the resistor can dissipate heat effectively while still having an efficient electrical connection to the surrounding circuit. When the current passing through the resistor increases, the resistance within the resistor begins to increase, allowing less current to flow through the circuit.

When the current passes through the resistor, the heat released is absorbed by the surrounding components, preventing excessive heat buildup in the resistor itself. This not only prevents the resistor from becoming too hot, but also prevents damage to any other components in the surrounding circuit. The heat also dissipates quickly, ensuring that the resistor does not remain too hot or overheat.

The MFR-25FRF52-402K is designed to be a reliable and cost-effective resistor for use in a wide variety of electrical applications. Its two-terminal structure makes it easy to connect to other components in the circuit, and its low insertion loss ensures that it does not cause significant losses in overall current. Its MIL-STD-202 standards and copper-clad laminates also make it a highly durable component, capable of withstanding a wide range of environmental conditions.
