Through Hole Resistors

Through hole resistors are resistors that are attached to the circuit board through the substrate. They are composed of a ceramic or porcelain material that is coated with a resistive material. The material can be either a metallic film or a carbon composition material. These resistors are often used when greater accuracy or reliability is desired, but they do have some trade-offs.

MF0207FTE52-2R26 Application Field and Working Principle

The MF0207FTE52-2R26 is a through hole resistor with a 2.26 Ohm resistance and a 10 Watt power rating. It is typically used in circuits where a predetermined voltage or current level needs to be maintained. These resistors are often used in lighting circuits as current-limiting devices, and they can also be used in audio circuits to hold signals within a certain level.

The working principle of through hole resistors is fairly simple. The resistor is composed of two electrical contacts connected to a ceramic or porcelain substrate. The substrate has a resistive material (usually metallic film or carbon composition) applied to it, and this material is responsible for dissipating electrical energy. When a current flows through the resistor, the resistive material causes electrons to be scattered, and this results in a voltage drop across the resistor. The magnitude of the voltage drop depends on the material used and the amount of current running through the resistor.

Through hole resistors are often used for current-limiting applications, as they are reliable and accurate. They can also be used in audio circuits to ensure that signals do not exceed a certain level. When selecting a resistor for a through hole application, it is important to choose one with the correct resistance value and power rating for the job.

Conclusion

Through hole resistors are components that are used to maintain a predetermined voltage or current level in a circuit. The MF0207FTE52-2R26 is a through hole resistor with a 2.26 Ohm resistance and a 10 Watt power rating, and it is commonly used in lighting and audio circuits. Through hole resistors are reliable and accurate, and they can be used for either current-limiting or signal-holding applications.
