Resistors are used in almost all electronic circuits. They are passive components that offer electrical resistance in order to reduce the current flow in a given circuit. There are different types of resistors, including through hole resistors, film resistors, and surface mount resistors. Through hole resistors, also known as "axial lead resistors", are components that have leads that are inserted through holes (or plated contacts) in the circuit board, with the leads soldered to the board after. Through hole resistors are some of the most commonly used resistors and can be found in just about any electronic device.

MFR-25JR-52-430R is a through hole resistor. It is a ¼ watt resistor with a tolerance of ±5%. Visitors can identify this resistor by “MFR-25JR-52-430R” printed on the body. MFR-25JR-52-430R’s application field includes but not limited to power regulators, power conversion, timing and frequency circuits, for military, telecommunications and medical equipment.

MFR-25JR-52-430R is designed with metal oxide film technology. Constructed with a ceramic rod, the winding, and two metal endcaps, the winding is then coated with a special metal oxide film to have excellent properties, such as low temperature coefficient, low noise and reliable conduction. The core and winding are then assembled and filled with a non-tracking epoxy that resist harsh environments.

When MFR-25JR-52-430R is placed in a circuit, it acts like a voltage divider. This causes the amount of current flowing through it to be reduced. The amount of voltage dropped is determined by the ohmic value of the resistor and the amount of current passing through it. By adjusting the resistor’s value, one can adjust the voltage drop in their circuit and thus control the current flow. MFR-25JR-52-430R has a resistance of 430 Ohms, which will create a voltage drop of 1.885V with a current of 4.3mA.

The main advantage of using a through hole resistor over a surface mount or film resistor is that it is much easier to replace because you don’t have to solder any components. The user simply disconnects the existing resistor and replaces it with a new one. Through hole resistors are also more reliable than other types of resistors because of their improved stability and better thermal properties.

MFR-25JR-52-430R’s terminal spacing is 2.5mm (0.1in), allowing it to fit into tight spaces and densely packed printed circuit boards. Its extended leads also makes it easier to locate and mount on the circuit board. Through hole resistors are typically used when the leads need to be bent to form a particular shape or when higher voltage and power ratings are necessary.

In summary, MFR-25JR-52-430R is a through hole resistor used for various purposes ranging from power regulators, power conversion, timing and frequency circuits to military, telecommunications and medical equipment. Its notable characteristics include its ease of mounting, its small profile and its reliable performance.
