Through Hole Resistors

Through hole resistors are components widely used in modern electronics, typically for power dissipation, signal conditioning, and voltage division purposes. The HTM250JR-73-40K is an example of a through-hole resistor. It is a 200-watt resistor with a resistance of 40K ohms.

Application Fields

The HTM250JR-73-40K through hole resistor is primarily used in the automotive, HVAC, and industrial markets. In the automotive industry, it is used to regulate voltage and resist high amperage. It is generally used in applications where cost-effectiveness is important, such as in the manufacture of cars. In HVAC, it is used to provide circuit protection by limiting current. Lastly, in the industrial sector, it is commonly used in applications that require heavy-duty performance, such as in power supplies or motor control circuits.

Working Principle

The HTM250JR-73-40K through hole resistor works on the principle of resistive heating. This is when electricity is passed through a high resistance material, causing it to dissipate heat. The resistor uses a copper-clad mica core with a resistance band. As current passes through this element, the heat produced is dissipated into the environment. This heat is also regulated to a safe level by a thermistor that is attached to the resistor.When electricity passes through the resistor, it creates a voltage drop due to the resistance of the material. This voltage drop is used to regulate the current in the circuit, thus preventing damage due to excessive voltages. The resistance of the resistor can also be adjusted by changing out the resistance wire.

Conclusion

The HTM250JR-73-40K through hole resistor is an ideal component for applications in the automotive, HVAC, and industrial markets. It is an effective way to provide circuit protection and regulate current. Furthermore, its adjustable resistance capabilities make it a great choice for a wide variety of applications. This resistor is highly reliable and can provide years of service in many applications.
