Fixed Inductors

Inductors are electrical components which are designed to store electrical energy in a magnetic field when a current is applied to them. The most common type of inductor is a fixed inductor, which has a set magnetic Strength and field geometry. Examples of this type of inductor are the 2256-42J series.The 2256-42J series is a series of 20mm (0.8") diameter, fixed inductors used in a variety of applications. The inductors are designed with an NPO dielectric core and an enameled copper wire winding, making them capable of operating at temperatures up to 130°C. With their small size, low ESR, and low temperature coefficient, they are well-suited for high frequency switching applications where space is limited.The 2256-42J series has a wide range of inductance values, ranging from 1.0uH to 470uH, making them suitable for use in a variety of circuits. They are typically used in DC-DC converters, as well as in EMI filter circuits and circuit amplifiers.The working principle of a fixed inductor is quite simple. When a current is applied to it, the inductor stores energy in the form of a magnetic field which surrounds the core of the inductor. This field is proportional to the applied current and is dependent on the inductance value of the component. As the current is changed, so is the magnetic field, causing the voltage across the inductor to change as well.The main advantage of fixed inductors is that they can be used in high frequency switching applications which require tight control of the voltage across the inductor. Additionally, their small size and low parasitic capacitance makes them ideal for use in noise-sensitive circuits.The 2256-42J series of fixed inductors are a great choice for applications where space is at a premium, or when high frequency and/or noise-sensitive circuits are needed. With their wide range of inductance values and high temperature rating, they are the perfect component for those looking to maximize performance in their designs.
