Through Hole Resistors

Through hole resistors such as the SFR25H0008459FR500 are typically used when high power needs dissipating, or in applications where a small form factor is critical. These resistors offer a wide variety of benefits and capabilities, so selecting the correct piece for a given application requires understanding the device\'s overall working principle and application field.

Working Principle

Through hole resistors are devices that act to reduce or limit the current that passes through a circuit. They work by creating an electrical resistance that impedes the flow of electricity. Specifically, resistors are designed to convert electrical energy to heat energy by introducing a certain amount of resistance into the circuit. The amount of resistance, also known as ‘impedance’, is based on the size of the resistor and the material used in its construction.Through hole resistors are available in a wide variety of sizes, shapes, and materials. The most common construction method is to use a coil of resistive material that is encased in a ceramic or plastic housing. The resistive material is typically a metallic alloy or mixture of carbon or carbon-loaded polymer. The coil is then attached to metal or ceramic terminals at either end with a lead wire or other type of connector.

Application Field

Through hole resistors are commonly used in power systems, signal processing, and quantification. Because of their high-power rating and small form factor, these resistors are often used in high-reliability, compact power systems, such as those found in airliners and military systems.For example, in power systems, through hole resistors are used to create a load of known value that will reduce system-wide losses such as heat loss or voltage drop. By introducing resistance into the system, the resistor acts to reduce the effective voltage or current, making it more efficient and reliable. These components are also used to dampen signal parameters such as overvoltage or spikes.In signal processing applications, the primary benefit of through hole resistors is their ability to help reduce unwanted signals, thereby improving the signal-to-noise ratio and thus, the accuracy of measurements. By introducing a certain amount of resistance into the circuit, the components help reduce or dampen disproportionate input signals, resulting in improved signal accuracy.In quantification applications, through hole resistors are used to measure quantities such as voltage, current, and resistance. By introducing a known resistance into the circuit, the components allow for accurate measurements to be taken.

Conclusion

The SFR25H0008459FR500 through hole resistor is a high-performance component designed for use in high-reliability, high-power, and compact systems. By introducing resistance into the circuit, the device helps reduce losses, improve signal accuracy, and facilitate accurate measurements. Through hole resistors are widely used in power systems, signal processing, and quantification applications.
