Fixed inductors, also called the choke inductor, are components used to store energy in a magnetic field. They can be used to filter out unwanted frequencies, provide impedance matching to a circuit, or decouple AC and DC circuits. The B82442A1472K000 is a fixed inductor that operates in temperatures ranging from -55°C to +130°C. This specialty component is designed for industrial applications, including automotive and motor controllers.

The B82442A1472K000 is a high-powered inductor capable of handling up to 10A at 100kHz with a saturation current of 15A. Its low-frequency insulation resistance is greater than 100MΩ, and its resistance is adjustable from 0.5 to 3.6mΩ. It is composed of a metal core and a winding that is encapsulated in durable epoxy. The size of the B82442A1472K000 is a 34.5mm x 14.7mm x 14mm, making it a relatively small component.

The B82442A1472K000 has a wide range of applications due to its compact size and reliable performance. It is used in audio equipment, motor controllers, power-supply regulators, analog circuit blocks, multi-pole filter circuits, and smoothing networks. The component is especially useful in automotive electronic systems due to its low attention to EMI/RFI noise interference. Its high inductance values and saturation currents make it suitable for switching power-supply applications requiring high peak currents.

The working principle of the B82442A1472K000 is quite simple. When current passes through the winding of the inductor, a magnetic field is generated around the component. This field stores the energy of the current and produces a back EMF, which is proportional to the rate of change of the current. Depending on the design of the inductor, this back EMF can be utilized to filter out higher frequencies or provide impedance matching. It is this property of a fixed inductor that makes it so useful in electronic circuits.

Overall, the B82442A1472K000 is an incredibly useful fixed inductor that is ideal for many industrial applications. Its small size and robust performance make it suitable for automotive and motor control applications, as well as audio equipment. The component operates in temperatures ranging from -55°C to +130°C and is capable of handling peak currents up to 10A. Its working principle relies on the generation of a magnetic field around the inductor, which creates a back EMF proportional to the rate of current change.
