Fixed inductors are common devices used in electronic circuits to store electrical energy in the form of magnetic fields. The 0925R-393H is one such inductor, and it is used in a variety of applications. Let us explore the application field and working principle of the 0925R-393H inductor.

The 0925R-393H is a radial-leaded, surface-mount chip inductor, designed to be used in low-power AC and DC applications. Thanks to its low profile construction, it is also suitable for use in very tight spaces. This makes it an ideal choice for a wide range of designs. Some of its common applications include use in analog circuits, filters, resonators, DC-DC converters, and EMI noise suppression. It can also be used in automobiles and other mobile environments.

The 0925R-393H is derived from the SMD 0925 footprint, and fits into any 9.25mm x 9.25mm surface-mount layout. It has a reference designator of ‘R’, and a range of product codes (e.g. 393H) which correspond to different inductance values. In the case of the 0925R-393H, this is 393H, meaning that the inductance value is 0.393uH. The 0925R-393H has a variety of parameters, such as inductance, Q-factor, DC resistance (DCR), maximum current rating (Irms) and dimensions.

The most important parameter of the 0925R-393H is its inner working principle. An inductor is a passive electrical device for inductance, which is a type of resistance that opposes changes in current. It works by converting electrical energy into magnetic energy, and then converting back into electrical energy when the current is interrupted. In the case of the 0925R-393H, it uses its thin core of ferrite material to store energy, and when an alternating current is implemented, it allows it to pass through its windings with minimal resistance.

The 0925R-393H’s inductance is measured in Henries (H) and is determined by its core material, number of turns of the windings and the size of the core. The Q-factor measures the ratio of maximum power (Qp) to the actual power (Qr) stored within the device. The DC resistance measures the amount of electrical resistance between the two opposing ends of the winding. The maximum current rating (Irms) is the maximum amount of electric current it can withstand without being destroyed. Finally, the dimensions are important because the inductor must fit correctly in the circuit board purchased for it. The 0925R-393H also has a high temperature range and is UL listed.

In summary, fixed inductors are used to store electrical energy in the form of magnetic fields, and the 0925R-393H is an ideal choice for low-power AC and DC applications. It fits into a 0925mm x 09.25mm surface-mount layout, and has a range of parameters such as inductance, DC resistance, and Q-factor. Its inductance is determined by its ferrite core material, number of windings, and size of the core, and its components can withstand a high temperature range. Thanks to its low profile construction, the 0925R-393H is suitable for use in tight spaces, making it an excellent choice for a variety of designs.
