Fixed inductors, also known as chokes, are electrical components used to store energy in the form of an electromagnetic field and provide inductive reactance when connected in a circuit. The CD43NP-2R2MC is a type of fixed inductors typically used for high-frequency applications where small size and low equivalent series inductance (ESL) are essential. Its versatile design makes it suitable for a wide range of applications including power-supply filtering, dc-dc converters, and radio-frequency (RF) circuitry.

The main components of the CD43NP-2R2MC are a ferrite core and copper coil. The ferrite core provides an effective flux path, while the copper coil enables the inductor to effectively store and release energy. The CD43NP-2R2MC has a rated current of 2.2A, an inductance of 2.2μH ± 20%, and an operating temperature range of -25 to +125°C. It also has a good temperature coefficient, low profile, and high inductance. Additionally, it is non-polarized, meaning it has no preferred direction of current flow.

In terms of its working principle, the CD43NP-2R2MC stores energy in the form of an electromagnetic field. When an electrical current passes through the inductor, a magnetic field is generated. The change in this magnetic field produces a secondary current. This secondary current is the main source of inductive reactance in the circuit. The inductor resists the flow of current, thus creating an energy gap in the circuit.

The CD43NP-2R2MC is a popular choice for a variety of applications. It is mainly used for filtering and pulse-forming circuits in switched-mode power supplies, such as in vehicles and laptops. It is also used in audio-visual equipment, servo-motors, and antennas. Furthermore, it is suitable for applications that require low ESL, low ESR, and high-frequency operation.

In conclusion, the CD43NP-2R2MC is a versatile fixed inductor designed for high-frequency applications where size and ESL matter. Its features and properties make it suitable for various applications due to its high inductance, low temperature coefficient, good temperature range, and non-polarized design. The CD43NP-2R2MC works by storing energy in the form of an electromagnetic field, which is then released in the form of an inductive reactance when a current passes through it.
