Introduction to Fixed Inductors

Fixed inductors are a key piece of electrical equipment used in many different applications. They are primarily used to create a stored energy field, or an inductance, and can be of various shapes and sizes to accommodate a variety of applications. The purpose of an inductor is to make an electrical current flow or resist a current flow, thereby providing additional control of the electrical current.Fixed inductors are used in many different types of electronics, including telecommunications, consumer electronics, medical and automotive applications. They are widely used for power regulation, filtering, signal conditioning and amplifying. Inductors come in various forms, ranging from magnetically shielded, surface-mount, leaded, and through-hole components. Each type has specific characteristics and benefits that make them suitable for different types of applications.

DRA124-471-R Fixed Inductor

The DRA124-471-R fixed inductor is an axial lead, low-profile, high-current inductor designed specifically for use in power supply circuits. It has a high spiral winding, allowing for more inductance in a smaller package. The inductor is made of a copper coated aluminum core that can operate at frequencies up to 1 MHz.The DRA124-471-R is designed for high current applications and can handle up to 6A of current. The inductor has a very low DC resistance of .05Ω, making it ideal for low-loss switching applications. It also has a very low profile of 2.5/3mm, making it ideal for space-constrained applications.

Working Principle of the DRA124-471-R

The DRA124-471-R works on the principle of the electromagnetic field that is created when a current is passed through a coil. This current creates an electromagnetic field, which then creates a varying magnetic field around the inductor. As the current passes through the coil, the varying magnetic field creates a resistance, thereby creating the inductance. The inductance created by the electromagnetic field is proportional to the size of the inductor, and it determines how much current can pass through the inductor. The higher the inductance, the less current can pass through and the lower the inductance, the more current can pass through.

Applications of the DRA124-471-R

The DRA124-471-R fixed inductor is primarily used for power supply applications, such as switching power supplies. It is also used for high-current applications, such as LED lighting and power conversion. Due to its compact size and low profile, it is also suitable for consumer applications such as mobile phones and laptops.In addition, the DRA124-471-R is also well-suited for automotive applications and can be used in applications such as fuel injectors, spark plugs and ignition systems.In summary, the DRA124-471-R is an ideal choice for applications requiring high current and space-constrained designs. It is widely used for power regulation, filtering, signal conditioning and amplifying. Its low DC resistance and high inductance make it ideal for low-loss switching applications. It is the perfect choice for applications that require power, performance and reliable operation.
