DRA74-330-R

Introduction

Fixed inductors (also known as fixed coils) are passive components in electronic circuits that are composed of coil and core materials, mainly used for energy storage and AC signal filtering. Fixed inductors are widely used in power supply circuits, signal filtering and signal blocking. DRA74-330-R, a product produced by Yageo Corporation, is a fixed inductor with 33Ω inductance value, which is suitable to use in compact circuits with limited space.

DRA74-330-R Application Field

The DRA74-330-R fixed inductor is a product made of ferrite material which is suitable to use in DC power supply lines, input signals, and power filtering circuits. Its easy for installation because of its surface mount type. It has a wide range of applications in various types of electronic products, such as switching mode power supplies, standby circuits, and inverters.

DRA74-330-R Working Principle

The basic working principle of fixed inductors is the Faraday law of induction, which states that a changing electrical current will induce a voltage across a conductor. This law is used to explain how an inductor stores energy. Inductors are made of a magnetic material, usually iron or ferrite. When a current passes through the inductor, the magnetic field created by the current will cause a voltage to be induced across the inductor.

The DRA74-330-R fixed inductor is made of ferrite material, which produces an alternating magnetic field when a current passes through it. The alternating magnetic field induces a voltage on the inductor, which is then stored as energy. This energy is used to filter noise and reduce ripple, making it ideal for DC power supply circuits.

Conclusion

The DRA74-330-R is a fixed inductor product produced by Yageo Corporation that is suitable for use in DC power supply lines, input signals, and power filtering circuits. It is made of ferrite material and operates according to Faraday’s law of induction. The alternating magnetic field created by the current passing through the inductor stores energy, allowing it to filter out noise and reduce ripple in DC power supply circuits.
