Fixed inductors are electronic components that have been used in a variety of circuits for decades. They store electromagnetic energy within a tightly wound core of conductor, and then release it in a controlled manner. The 49681SC is one of the most commonly used inductors today, and its application and working principle can be further discussed.

Application Field of the 49681SC

The 49681SC, with a coil resistance of 1.2Ω, is suitable for wide range of applications that require filtering and energy storage. For instance, it can be used as a low pass filter in audio systems, providing high-frequency audio signals to be filtered out, and preventing them from being amplified or reproduced. In addition, it can also be used in power supply circuits to provide a controlled current output, and limit ripple in the output.

The 49681SC is often used for applications requiring moderate current ratings due to its high saturation current, which is the maximum current that can be passed through the core without causing any damage. This makes it well suited for use in highly transient circuits. It is also widely used in signal conditioning circuits since it has excellent temperature stability, allowing it to remain stable under hot and cold conditions.

Working Principle of the 49681SC

The working principle of the 49681SC is based on Faraday’s Law, which states that when a changing magnetic field is applied to a coil of wire, electricity is induced in the wire. This is known as electromagnetic induction. In the 49681SC, this principle is used to store energy in the coil; when a charge of electricity is applied to the input of the inductor, it induces a magnetic field in the core, and this stores the energy within the coil, which can then be released in a controlled manner when the current is stopped.

The 49681SC also benefits from the fact that when the inductor is connected to a circuit, the current flowing through it increases progressively, which is known as its inductive reactance. This property can be used to reduce the amount of current passing through the circuit, and is particularly useful for applications requiring high current load protection.

The 49681SC can also be used for applications that require higher isolation, such as in power supplies. When a voltage is applied to the coil, the induced current causes a magnetic field to be generated in the core, which can then be used to provide insulation between the input and output of the supply.

Conclusion

The 49681SC is a popular inductor that has a wide range of uses due to its low coil resistance, high saturation current, and excellent temperature stability. Its working principle is based on Faraday’s Law, which enables it to store and release energy in a controlled manner. In addition, its inductive reactance can be used to reduce current passing through the circuit, and its magnetic field can provide insulation between the input and output of the supply. All of these features make the 49681SC an ideal inductor for a variety of applications.
