Fixed Inductors

CW160808-8N2D Application Field and Working Principle

Fixed inductors, also known as inductors, are electronic components that store energy in the form of a magnetic field. A relatively constant magnetic field is generated and stored in a coil-shaped core material, with varying levels of resistance to changes in the electrical current passing through it. As such, fixed inductors are widely used in circuits for a variety of applications. Examples include power supplies, communications systems, televisions, and motors.

The CW160808-8N2D is a novel type of fixed inductor, designed for precision use in highly compact circuits. Its small size enables it to be integrated into densely populated boards. The inductor measures 8.0 mm (W) × 8.0 mm (L) × 5.1 mm (H), with a 25.3-mm lead span. Furthermore, its windings are produced from magnet wire with a high dielectric strength that ensures superior quality and resistance to electrostatic discharges. Its high powder core further enhances its stability and performance.

Working Principle

Fixed inductors create a magnetic field when current passes through them. The magnitude of this magnetic field depends on the inductance of the inductor, which is a product of its coil structure and magnetic characteristics. When an alternating current or voltage source is applied to the coil, the magnetic field, and consequently the current, rises and falls in a cyclic manner. This induces a resistance in the inductor, since a changing magnetic field also changes the self-induced voltage within the coil. This simultaneous variation in current and voltage is what produces inductance and the desired electronic effects.

The self-inductance of an inductor is related to the electromagnetic energy stored in its magnetic field. This energy is equal to the inductance multiplied by the square of the current passed through the inductor. The CW160808-8N2D is designed to hold, and remain stable at, higher current levels than traditional inductors. This makes it an ideal choice for the tight and precise current demands of small and densely populated circuits.

Applications

The CW160808-8N2D is suitable for all kinds of fixed inductor applications, including power supplies, RF communications, automotive, smart meters, HVAC systems, and consumer electronics. Its low size and high energy storage capabilities make it an excellent choice for building high-density circuits. Furthermore, its compatibility with miniature circuits makes it useful in projects that require no-compromise performance in a small form factor, such as hearing aid and medical device circuits.

The CW160808-8N2D also demonstrates notable cost efficiency due to its easy-to-install, low part count. This contributes to a lower product BOM (Bill of Materials), while still providing steady performance. Its superior quality and reliability further increase its value in the today’s highly competitive electronic market.

Conclusion

The CW160808-8N2D is a highly reliable and cost-effective fixed inductor for a variety of circuits. It offers unmatched performance in a compact size and is suitable for a broad range of applications, from consumer electronics to medical devices. Its superior quality and low part count will continue to be valuable additions in any project.
