Fixed Inductors

Inductors, also known as coils, chokes, or reactor are electrical components that have a positive temperature coefficient of resistance. They can be categorized into two types: fixed inductors and variable inductors. A fixed inductor is a two-terminal component whose inductance can be predetermined by selecting the correct "air gap" during design and construction. Variable inductors allow adjustment of the inductance through some means. Both types are widely used in a variety of applications.

2534-42K Inductor Application Field and Working Principle

The 2534-42K inductor is a fixed inductor primarily used in the fields of high-frequency switching power supplies and related operations. This inductor can be used in applications such as AC/DC converters, off-line switching power regulators, and switch mode power supply drives. The 2534-42K inductor features a reliable and stable electrical performance, efficiency, durability, and low noise because of its excellent construction design.

This inductor operates according to Lenz’s Law, which states that a current-carrying conductor produces a magnetic field and a changing magnetic field produces a current in an opposing conductor or inductor. The design of the 2534-42K inductor allows an air gap to be set, deciding the inductance value. The use of a magnetic core with an air gap results in a higher magnetic flux, allowing the inductor to have a higher induction performance compared to other types of inductors.

The 2534-42K inductor is constructed in an axially wound, flat bobbin-style, which can be printed with a variety of different shapes based on the customer’s needs. The bobbin-style construction allows the size of inductor to be much smaller than traditional designs, making them more suitable for use in compact end products. They are also typically rated at 20 A, meaning they can still maintain a very high current capacity in a tiny form factor.

The 2534-42K inductor\'s low DC resistance (< 0.4 Ohms) allows them to be suitable for applications such as high-frequency operation or battery charging. These inductors also have an excellent SRF performance, with frequencies ranging from 1 MHz up to several hundred MHz. The design of the 2534-42K inductor also permits low leakage field flux, keeping noise level low.

The 2534-42K inductor is ideal for applications such as AC/DC converters, off-line switching power, and switch mode power supplies/regulators due to its high levels of efficiency, excellent magnetic flux characteristics, and low noise. It also has a high current capacity and a low DC resistance, making them perfect for use in high-frequency operations or battery charging.
