Fixed inductors are passive components used to store electrical energy in the form of a magnetic field. They consist of a coil of insulated wire wrapped around a core material, such as ferrite, iron, or air. The wire is connected to two leads, one at each end, to create an electrical circuit.

HKQ04021N0C-E is one example of a fixed inductor. It is a small, molded SMD power inductor designed for high-frequency operations in switch-mode power supplies. It is low profile and Surface-mountable, making it suitable for a wide range of applications.

The HKQ04021N0C-E has a wide range of applications, including DC/DC converters, switching power supplies, charging circuits, and amplifier circuits. It is also used as a power filter to reduce transient noise. It can also be used for larger-current applications, such as electric vehicles and home appliances.

The inductor works by storing electrical energy in the form of a magnetic field. When current flows through the coil, it creates a magnetic field, which then magnetically couples with the core material. This creates an inductance, which slows the current and converts it into electrical energy.

The HKQ04021N0C-E has a maximum operating temperature of 125°C, which makes it suitable for high-temperature applications. It also features a high current capability of up to 3.2A and low DCR for improved efficiency. It is available in 0402, 0603, and 0805 package sizes.

Overall, HKQ04021N0C-E is a versatile, low-profile, surface mountable inductor that is suitable for high-frequency operations and high-temperature applications. It is well suited for use in DC/DC converters, switching power supplies, charging circuits, amplifier circuits, and power filters.
