Fixed inductors, also known as chokes, are standard components that are composed of a coil of wire wound around a magnetic core. Widely used in electronics circuits, these devices provide electrical noise or electromagnetic interference (EMI) suppression and allow filtering of frequencies to enable the electronic circuit to operate as intended. The L0603B220MDWFT fixed inductor is an especially important component in high volume, commercial electronic applications, where its small size, high efficiency, and reliable performance can have a substantial impact on the operation of a product.

The L0603B220MDWFT is a surface-mount technology (SMT), fixed inductor that comes in a miniaturized, low profile package. This makes it suitable for a variety of applications despite its small size, including audio, power supplies, computers, and communications equipment. This SMT fixed inductor is rated for 20 amps continuous at 25°C, and is available in a standard tolerance of ±20% with its inductance value being marked on the device straight away or detectable using an LCR meter.

The L0603B220MDWFT fixed inductor is typically used in power conditioning applications. It is often placed between the switch mode regulator and the power input of a circuit to filter input voltage and current, meaning that it restricts the magnitude of changes in the voltage while ensuring that the operating speed of the switch mode regulator is maintained. It is also commonly used in numerous switched-mode power supply (SMPS) and voltage regulator applications.

The L0603B220MDWFT basically works by providing a low impedance path for the Alternating Current (AC) particularly with high frequency signals. Thus, these high frequency signals are diverted around the electrical components that it is protecting and then stored within the component’s magnetic field. This process allows the circuit to maintain a constant voltage and current output, while suppressing electromagnetic interference.

Aside from its countless uses in power applications, the L0603B220MDWFT fixed inductor can also act as an oscillator, producing an AC signal at a specific frequency. In fact, these circuits are commonly deployed as "oscillator circuits". These oscillators range from simple circuits where the L0603B220MDWFT serves as the only inductor, to complex systems where the inductor serves as part of a harmonic generator.

As such, the L0603B220MDWFT fixed inductor is an indispensable part of many circuits, serving a variety of electrical purposes. As it is available in a wide range of inductance values, it can be used to match the requirements of multiple circuits with a minimal impact on space or size. Furthermore, the L0603B220MDWFT surpasses most of the other surface mount inductors due to its low cost, high surface area, and efficiency.
