A fixed inductor, commonly known as a coil or reactor, is an electronic component that stores energy in a magnetic field. It is most commonly used in circuits to add inductance. The 2256R-39L is a fixed inductor from the 2256R series manufactured by Kubler. It has a maximum operating temperature of 125°C and a rated current of 39A.

The 2256R-39L is a radial-leaded inductor with a 20.5mm diameter and a 5.2mm height, suitable for surface mounting. It has a heavy-duty construction, with a maximum winding temperature of 120°C and an insulation sleeve. It features a high saturation current, low resistance and a low equivalent series resistance. It also has a good self-resonance usually above 10MHz frequency.

The 2256R-39L is typically used in high switching frequency DC-DC converters. It is often found in power supply circuits, motor controllers, and other applications that require high Ripple current and temperature stability. It is a reliable and robust inductor, ideal for signal filtering.

The working principle of a fixed inductor is based on the relationship between electricity and magnetism. Magnetic fields are generated when an electrical current passes through a wire coil. This in turn induces a magnetic field within the coil. The induction of an electric current in the coil is the result of the magnetic field generated. The stored energy in the coil’s magnetic field is then released as an electric current when the current stops.

The strength of the induced voltage in a coil is determined by its inductance, which is determined by its physical characteristics such as the number, length and diameter of turns in a coil of wire. The 2256R-39L has a maximum inductance of 82mH, making it suitable for applications requiring high-current handling capability. It also has a high saturation current, low equivalent series resistance and good temperature stability.

The 2256R-39L is a versatile inductor that can serve in a variety of applications as an efficient regulator or filter. Its ability to handle high currents makes it an ideal choice for use in DC-DC converters, motor controllers, and power supplies. Its robust construction, good self-resonance, and high saturation current ensure reliable performance and long lasting life.
