Fixed inductors are widely used in electronic circuits, ranging from power supplies and motor driver circuits to audio amplifiers and RF circuits. The MHQ0402PSA16NHT000 is a fixed inductor from the Murata Electronics series which is specially designed for high-frequency circuits operating in the frequencies ranging from 200MHz to 3GHz. The device is small in size at 2.0x2.0x1.6 mm, making it easy to accommodate inside electronics which need to be compact in size.

The use and application of these inductors is predominately seen in the field of power electronics, especially in power converters like DC to AC inverters, where they are used mainly for energy storage. Moreover, it is extensively used in motor drives and low-frequency power switch circuits, where a moderate amount of energy storage is needed. They are also used in the power factor correction circuit and switching power supply control circuit.

The MHQ0402PSA16NHT000 fixed inductor uses a multi-layer winding structure of the magnetic core, which is laminated by ferromagnetic materials, and a high-grade magnetic alloy is used for the magnetic core. The unique magnetic field distribution of the winding structure and the internal structure of the magnetic core are designed to effectively reduce eddy current losses. The high permeability of the magnetic core also increases the inductance of the winding which is necessary for the stability of the circuit.

These inductors also have a low loss equivalent series resistance (ESR) and its operating temperature range is -40°C to +85°C. It is also UL94V-0 recognized and features an Epoxy surface coating that ensures the mechanical and insulation reliability of the inductor.

MHQ0402PSA16NHT000 fixed inductors can also be used in radio-frequency circuits. Due to its high frequency characteristics, it has a wide range of applications in radio and television communications and in other electronic devices in which the frequency range is relatively higher.

As the device is designed for high-frequency circuits, it also has a wide range of features and characteristics specifically designed for this purpose. These include a high self-resonant frequency, a low parasitic capacitance, a low inserted loss and a good temperature characteristic. The higher the self-resonant frequency for a given inductance, the better the device will be at handling higher frequencies. It also has a better performance than a low self-resonant frequency device at these frequencies. The resistance across the inductor is kept to a minimum due to its excellent saturation characteristics.

The MHQ0402PSA16NHT000 fixed inductor also features a high magnetic shielding effect, which is beneficial for reducing electromagnetic interference (EMI). The inductor\'s small size also enables it to fit in places where space is limited. All these characteristics make this fixed inductor suitable for a wide variety of applications, from power converters to low-frequency power switch circuits.
