Fixed inductors are a type of electronic component used in electronic circuits to store energy in a magnetic field, often made from coiled copper wire and a ferromagnetic core, such as iron or ferrite. The most common application of fixed inductors is to reduce the radiated emissions of a circuit, by providing a low-impedance path for high-frequency currents.

B82141B1222K9 fixed inductor is one of most popular inductors available in the market. It is a common mode choke designed for high current circuits. This magnetic component has a high inductance value, which enables it to reduce electromagnetic interferences, thereby increasing the signal integrity of the device. It consists of 2 x 1.3 mm2 coils (each one consists of 18 turns) with a total outer dimension of 39.5x39.5x22.0 mm. Its rated current range of 13.3 A yoke and 5.2 A coil make it ideal for high-current applications such as motor drivers, power supplies and lighting systems.

The working principle of a fixed inductor is based on the fact that electricity induces a magnetic field. When an electric current is applied through the inductor, it creates a magnetic field around the core of the inductor. This magnetic field contains energy, which the inductor then stores and releases back into the circuit. As the current in the circuit increases or decreases, the inductor will react accordingly by storing and releasing greater or lesser amounts of energy.

B82141B1222K9 fixed inductor has a working frequency range from 0 to 1 MHz and a DC resistance of 0.11 Ω. It is also protected against overcurrent, over-temperature and overload. In addition, it is UL recognized and RoHS compliant, meaning it meets all the safety and environmental requirements. It is used in automotive, industrial, home appliance and military applications. Other possible applications of this inductor include voltage regulator designs, dc-dc converters, low-dropout regulators, EMI filters and power supply design.

In conclusion, B82141B1222K9 is a fixed inductor with a high inductance value that can reduce electromagnetic interference. It is ideal for high current applications such as motor drivers, power supplies and lighting systems. It is also UL recognized and RoHS compliant, making it safe and versatile.
