Fixed inductors are electronic components that store energy in a magnetic field when electric current passes through them. The SDR0403-120ML is a type of fixed inductor, characterized by a wide range of application fields and working principles.

The SDR0403-120ML is typically used in applications requiring high current, such as in switching power supplies, microwave ovens, uninterruptible power supplies, and control circuits. It is also used in audio and communications equipment, personal computers, and other consumer-electronics applications. The SDR0403-120ML is also used in automotive and military applications that require high-current handling.

The SDR0403-120ML is manufactured by winding a coil of magnet wire around a special core material. The core material is responsible for the inductance value – the total amount of energy stored. When a current is applied, the core material produces an electromagnetic field proportionate to the amount of current being applied. This electromagnetic field in turn produces an opposing force to the current, creating an inductance.

The SDR0403-120ML has two primary winding configurations. One configuration consists of a single winding connected to two opposite pins. This configuration allows the device to respond to current in either direction. The second configuration consists of two windings, one in each of the two opposite pins. This configuration enables the device to have a higher inductance when the current direction is switched. This makes the SDR0403-120ML useful for applications with variable or changing current directions.

The SDR0403-120ML is a versatile device with adjustable inductance. By adjusting its inductance, the device can be tuned to operate most efficiently on specific frequencies or current ranges. This makes it ideal for use in applications such as switched-mode power supplies and switching networks.

The SDR0403-120ML is designed to be highly reliable, featuring high-temperature solderable terminations and a wide operating temperature range of -55°C to +125°C. It is available in a wide range of sizes, from 0402 to 1812 packages, and with inductance values from 0.1µH to 1000µH. The SDR0403-120ML is a robust and versatile device, making it an ideal choice for a range of applications.
