Fixed inductors are components used in the field of electronics, usually to store energy and provide electrical filtering, or to help shield other components from any interference. They come in multiple shapes and sizes, and the L-07W2N2SV4T is one such type. This particular type is a vertically mounted, leaded three-terminal inductor. It can accommodate a variety of popular specifications and includes features such as a low resistance, high self-resonance, and low induction capacity.

Application Field

The L-07W2N2SV4T is specifically designed for use in low current wireless applications, including smartphones, tablets, and other consumer electronics. It is also well-suited for use in telecom and automotive applications, where the small size and low-resistance make it ideal for use in limited space, without compromising performance.

The low DC resistance makes this type of fixed inductor a good choice for power supply smoothing. As a three-terminal inductor, this component is used for its power filtering capabilities, allowing for reduced ripple current in power circuits.

Due to the low self-resonance, the L-07W2N2SV4T can be used as an antenna for radio frequency (RF) or microwave communications. This type of inductor is generally used to create small, widely distributed inductors in order to reduce or eliminate the amount of parasitic capacitance found throughout the application. This in turn helps reduce interference and improve reliability in the RF/microwave system.

Working Principle

A fixed inductor is essentially a donut-shaped coil of wire, usually formed in the shape of a toroid, that acts as a type of transformer. It is composed of a core, such as iron or ferrite, and wound wire which creates both the primary and secondary windings. The core material helps to increase the inductor’s efficiency by concentrating the electromagnetic field around the winding.

Fixed inductors generate an electromagnetic field when current passes through it. This field induces a voltage in a secondary winding, thereby creating a transformer effect. The voltage induced by the electromagnetic field is inversely proportional to the amount of current in the primary winding—the higher the current, the lower the voltage. This effect is what enables the inductor to act as an energy storage device, ensuring steady-state power delivery to the circuit. Compare to the choke which generally maximizes the coupling between its windings and constrains the current in the circuit.

The amount of inductance an inductor is capable of producing is measured in henrys. A henry, named after the American scientist Joseph Henry, is the standard unit of inductance. A one-henry inductor will generate one volt for every ampere of current flowing through it.

The L-07W2N2SV4T fixed inductor is designed for use in low current, low voltage applications, such as those found in remote control and telecommunication systems. With its low self-resonance over a wide frequency range, and low induction capacity, this type of inductor is ideal for reducing unwanted ripple current, rejecting interference, and helping to ensure reliable performance across a variety of different application environments.
