Introduction to Through Hole Resistors

Through hole resistors are devices that are used to predictably and precisely regulate the amount of electrical current that is to pass through a circuit. These devices are highly important components in any electrical circuit. Without resistors, electronic circuits would not be able to achieve the desired features, functions, and performances. As an important part of the electrical components, through hole resistors are designed to have a specific conversion of power. This conversion of power is regulated by an electrical resistance that allows current to flow through a circuit. This conversion of power is critical in regulating the power supply in a circuit.

Application Field

Through hole resistors have a wide range of applications. They can be used in different areas of electronics including switching power supplies, consumer electronics, automotive electronics and industrial controls. SFR25H0002748FA500 Metal Film Through Hole Resistors can be used in applications that require 0.1W of power and have an operating temperature range of -55°C to +155°C. It can be used in any application that requires a high-quality and reliable 0.1W resistor with precise tolerance levels.

Working Principle

The working principle behind through-hole resistors is simple. When a voltage is applied across the terminals of the resistor, a certain amount of energy converts to heat depending on the resistance of the resistor. This conversion of energy from electric current to heat is known as Joule heating and is based on Ohm\'s law. As the energy converts to heat, the temperature of the resistor increases, resulting in a decrease of resistance of the resistor.

Conclusion

Through hole resistors such as the SFR25H0002748FA500 are essential components for many electronic applications. They are reliable and durable and can be used in a variety of applications that require precise resistance control. Through hole resistors have a consistent working principle, which allows the same performance to be delivered across a variety of devices and circuits.
