Through Hole Resistors

Through hole resistors are a type of resistor that, as the name implies, are constructed by being inserted through a printed circuit board (PCB) and soldered into place. They are often referred to as leaded resistors, due to their lead wires which expand from the sides of the component. This makes them a popular choice for applications where the resistor needs to be held down due to external forces or vibrations.

CFR3WSJT-73-240K Application Field and Working Principle

The CFR3WSJT-73-240K is a low resistance fixed-type through-hole resistor powerful device used for current-limiting and voltage-limiting purposes in various electrical and electronic circuits. Its wide range of resistances (7.3-240k) make it suitable for a variety of applications such as surge protection, power supply, motor control, amplifier, and voltage-limiting components, and it is also popularly used with digital communication devices.

The CFR3WSJT-73-240K operates by limiting the current flow through the resistor based on Ohm’s Law, which states that the current is directly proportional to the applied voltage over a given resistance. As the voltage across the resistor increases, the current flowing through increases as well. When the current reaches the rated power of the resistor, the voltage across the resistor will stabilize and will remain constant, thus limiting the current flow. This process is known as power dissipation.

The CFR3WSJT-73-240K is available in various power and resistance ratings from 7.3-240k, and is designed to dissipate heat generated by the power consumption of the resistor. Depending on the size and type of resistor, it may be mounted directly on a printed circuit board (PCB) or use hole spacing of between 8-15mm.

Due to its ability to limit current, the CFR3WSJT-73-240K is used in various applications such as motor controls, voltage and current regulation, surge protection, and general power supply regulation. It can be used in both digital and analog systems, and is suitable for high temperature environments as well as hazardous environments.

Conclusion

The CFR3WSJT-73-240K is a type of through hole resistor that is used widely for limiting current and voltage in various circuits. It is designed to dissipate heat generated by power consumption, and is available in various power and resistance ratings. It is suitable for use in both digital and analog systems, as well as in hazardous and high temperature environments.
