Fixed Inductors

Fixed inductors are component devices which store energy in the form of a magnetic field and are used as inductors or chokes in electrical and electronic circuits. The core material used to construct fixed inductors, such as CDC4D20NP-121KC, may range from ferrite, powdered iron, or air cores depending on the application. The inductors play a key role in many applications such as power electronics and control systems.

CDC4D20NP-121KC Application Field and Working Principle

CDC4D20NP-121KC fixed inductor is a 6mm*6mm magnetic core ferrite general-purpose inductor with current transformer applications. The inductor is constructed to solve power supply and electromagnetic interference (EMI) issues with ferrite beads.The inductor design features a rectangularly shaped, 3-contact through-hole construction, making it easy to mount in circuit boards. The contact pins of the inductor feature silver-plated finish, making it very reliable and able to handle high current applications. It offers a flat frequency response of 50MHz, allowing for a wide range of operating ranges from low to high frequencies.This proposed inductor is typically used in a pairing with a capacitor in order to create an LC filter, which is a type of circuit that filters out undesirable frequencies and improve signal quality overall. The construction helps create a stable, low impedance path for high-frequency signals and provides filtering for low-frequency signals.In terms of working principle, an inductor creates a magnetic field around it. When current passes through the inductor, it generates a voltage across its ends which opposes the direction of the current and is inversely proportional to the rate of its change. This is known as the inductance effect.This is helpful for controlling the current within the circuit as the voltage, through the process of Ohm\'s Law, is then applied to the load and is controlled depending on the inductance of the CDC4D20NP-121KC inductor used. As the load resistance is changed, the voltage remains the same, making it an effective device for controlling current characteristics within the circuit.The CCR4D20NP-121KC inductor has a wide range of applications and benefits which include:- EMI shielding and interference- High current applications- Low to high frequency performance-Stable, low impedance path- Improved signal qualityThe inductor is also highly reliable and cost effective compared to other solutions. Its construction and design allow it to be easy to install in circuit boards and requires minimal maintenance.The CDC4D20NP-121KC inductor is a great choice for general-purpose applications where high current handling, EMI and interference protection, and high signal quality are needed. The wide frequency response range allows for a greater number of applications, improving its efficiency and versatility.
