Fixed Inductors

Inductors, also known as coils, chokes or reactors, are devices used in electrical circuits to store energy. They can also be used as a filter component and can be very useful for some radio frequency applications. These inductors generally come in two main types: fixed and variable. The purpose of this article is to discuss the application field and working principle of the fixed inductor RCR875DNP-151K.

Application Field

Fixed inductors are mainly used in circuits when the application requires a constant amount of inductance. This is usually the case when a certain majority of the circuit\'s parameters remain constant over time. The RCR875DNP-151K inductor is particularly suitable for applications where a constant current is required, such as for a rectifier, voltage regulator, power supplies, and some low-frequency switching power converters. This type of inductor is also popular because its fixed inductance means that it has a fixed impedance across a range of frequencies, making it well-suited for radio frequency applications.

Working Principle

The direct current resistance of an inductor is usually small, meaning that the inductor behaves as a conductor for DC current. When this type of current passes through the inductor, it induces a magnetic field around the inductor, referred to as mutual inductance. This means that the electrical current is also creating a magnetic field which interacts with the external magnetic field that it is embedded in. As a result, the electrical current will be impeded in some way, either totally blocked in a DC circuit or slowed down in an AC circuit. This is the basis of the inductor\'s working principle. The RCR875DNP-151K inductor specifically uses a air gap and a ferrite core in its construction. This allows it to achieve a higher inductance value than traditional inductors.

Conclusion

In conclusion, the RCR875DNP-151K inductor is a fixed inductor that offers a wide range of applications due to its highly consistent inductance, high frequency handling capacity, and its ability to reduce the size of electrical circuits. This makes it an extremely useful inductor for applications such as rectifiers, voltage regulators, power supplies, and some low-frequency switching power converters. Its working principle is based on the induction of a magnetic field around the inductor, caused by passing DC current through it, which will impede the current in some way, either totally blocking it or slowing it down.
