Types of Through Hole Resistors

Through hole resistors are a type of passive electrical component that can adjust the electrical power flow in a system. Through hole resistors have two terminals, that can be orientated in either a vertical or horizontal direction. Most through hole resistors also have one or more insulating bases between their terminals, to provide electrical insulation between them.

Working Principle of the MFR25SFTF52-18R2 Resistor

The MFR25SFTF52-18R2 works by dissipating the electric power that is applied to it. This process is known as ohmic dissipation. As electric current runs through the resistor, it heats up, due to the resistive element as energy is dissipated or released as heat. The dissipation continues until the current stops flowing, and the resistor cools back down to its original temperature. The resistance of the resistor can also be increased or reduced based on the voltage applied to it. This is known as voltage dependent resistance and can be used to help stabilize or reduce the electric current in a system.

Conclusion

The MFR25SFTF52-18R2 makes for an ideal through hole resistor for precision applications. Its metal film construction enables it to handle higher power levels while enabling precise current and voltage regulation. It is also suitable for use in a variety of filter networks and high frequency circuits. While dissipating energy, it also works on a voltage dependent principle, allowing the current in a system to be stabilized or reduced as needed.
