Fixed inductors are components that store electrical energy in a magnetic field, allowing for regulated current flow. They are used in circuits for filtering, tuning and coupling. The HK21258N2K-T is an inductor that is particularly suited for circuits with higher currents and high frequencies, due to its high inductance and temperature stability.

The HK21258N2K-T is a surface mountable, low profile inductor with a height of just 1.6mm. Its low profile makes it ideal for compact and densely packed circuit designs. The heat dissipation capacity of this device is also impressive, making it ideal for high reliability applications such as automotive and industrial control equipment. It can handle currents up to 10A and frequencies up to 1GHz.

The operating principle of the HK21258N2K-T is based on Faraday’s Law, which states that the magnetic field produced by a current-carrying conductor is proportional to the rate of change of current through it. In a fixed inductor, this relationship is exploited to create a circuit that can regulate the current flow. As the current changes, the magnetic field produced by the inductor also changes, inducing an electromotive force (EMF) in the opposite direction. This EMF opposes the original current, thus keeping the current constant.

The HK21258N2K-T is used in various applications, such as DC-DC converters, low pass filters, high pass filters, resonance circuits, and voltage regulators. In DC-DC converters, it is used to step down the input voltage, regulate and filter the current. In low pass filters, the inductor blocks high frequency signals, allowing only low frequency signals to pass. In high pass filters, it is used to filter the high frequency signals. Resonance circuits rely on the inductor for producing a forced oscillating current and voltage at a certain frequency. And in voltage regulators, an inductor in series with the output and a diode is used to limit the current while maintaining a constant voltage.

The HK21258N2K-T is designed to provide high efficiency and excellent current handling capabilities, making it an ideal choice for a wide range of applications. Its high temperature stability and low profile make it ideal for use in densely packed circuits, and its wide operating range makes it suitable for use in a wide variety of conditions. Its advanced design also allows it to dissipate heat quickly, making it ideal for high reliability applications.
