UP0.4SC-3R3-R

Fixed Inductors

The UP0.4SC-3R3-R is a fixed inductor that is often used in applications such as circuits for providing power, low-pass filters, and radio frequency (RF) synthesis. Fixed inductors, also known as coils and chokes, are electrical components that are used to store energy within a magnetic field. These types of components are designed to work in conjunction with other components within a circuit, such as resistors and capacitors, to control current and voltage flow.

Design

Fixed inductors typically consist of a wire or core that is wrapped around a core material, such as a ferrite. When the current flows through the wire, it creates a magnetic field that stores energy. The magnetic field is then released when the current is stopped, releasing the stored energy. By increasing or decreasing the number of wraps around the core, as well as adjusting the type of core material, the characteristics of the inductor can be adjusted.

Applications

The UP0.4SC-3R3-R is an ideal component for applications such as providing power, low-pass filters, and RF synthesis. In power supply circuits, inductors are used to help control current and voltage levels. Low-pass filters are used to attenuate or reduce frequencies above a certain cutoff frequency. RF synthesis circuits are designed to synthesize complex waveforms for use in various communications applications, such as digital cellular phones.

Working Principle

The UP0.4SC-3R3-R fixed inductor works on Lenz’ law, which states that currents flowing in a coil create an electromagnetic field that sets up a secondary current in response. By changing the shape of the inductor core or the number of windings, the characteristics of the inductor, such as inductance, can be adjusted. When current is applied to the inductor’s terminals, the core’s magnetic field stores energy in the form of an electromagnetic field. Once the current is removed, the stored energy is released, producing a voltage spike.

Conclusion

The UP0.4SC-3R3-R fixed inductor is a versatile and reliable component for applications such as power supplies, low-pass filters, and RF synthesis. It works on the principle of Lenz’ law and is designed to store energy in a magnetic field and release it when the current is stopped. By changing the shape of the core material and the number of windings, the characteristics of the inductor can be adjusted.
