Through hole resistors, in the form of the FMF-25FRF52-68K, are components used to reduce current flow or provide a precise voltage drop across a circuit in order for the circuit to function properly. As the name implies, these resistors are designed for installation through a mounting hole or ground in the circuit.

The FMF-25FRF52-68K is a fixed-value resistor that is designed to resist a specific amount of voltage. It features an axial leaded, through-hole package with a body diameter of 2.5mm and a lead spacing of 0.75mm. The resistor is rated at 68 Kilo-ohms with a tolerance of 10%, a working power of 1/8 watt at 70 °C and a temperature coefficient of 100ppm/C.

The resistor serves two primary purposes. First, it limits the amount of current flowing through a circuit, guarding against the risk of short circuits. This is critical for helping to ensure that the correct voltage and current are delivered to each electronic component in the circuit. Without this safeguard, too much current can flow into devices that are not designed to handle it, resulting in system malfunctions or damage.

In addition, resistors are also used to create precise voltage drops across a circuit. When power is supplied to a circuit, the resistor forces some of the electricity to “jump” across the gap it provides, creating a specific voltage value. This is useful for providing a specific operational level for certain parts of the circuit, such as amplifiers or processors.

The FMF-25FRF52-68K is constructed from a ceramic core with three metal layers wound around it for maximum durability and heat-resistance. Each component is then sealed in a protective layer of epoxy to provide insulation against electrical surges. This also helps to protect against accidental contact with other components, ensuring that the resistor has a longer lifespan.

In summary, through hole resistors are essential components used in a wide variety of electronic circuits. The FMF-25FRF52-68K is one example of these resistors, which features a 68 Kilo-Ohm rating, a working power of 1/8 watt, and a temperature coefficient of 100ppm/C. This resistor serves two key purposes: limiting current flow and creating precise voltage drops to operate specific parts of a circuit.
