Fixed inductors refer to inductors with fixed inductance. They are widely used between capacitors and resistors in electrical circuits to suppress interference and create resonance circuit or filter circuit. SD7030-101-R is one of such inductors, used to generate high current at radio frequencies, allowing for most radio circuits with resonant frequency in the range of 1˜500MHz. It is also applicable to circuits that require high speed switching.

SD7030-101-R fixed inductors are wound with air core, providing high-performance power inductors. The inductance of these inductors is highly stable, together with extreme resistance to vibrations, enabling it to perform in hostile environment. It also features low losses that will help to minimize the thermal footprints in the application.

When working with SD7030-101-R inductors, it is important to consider inductance, current saturation, size and cost. The inductor usually comes in a small size and features high RF efficiency and excellent current carrying capabilities. Depending on the application, the inductance of the inductor can be varied to get the desired resonance frequency and filter response.

The main application of the fixed inductor SD7030-101-R is in radio frequency circuits. This particular type of inductor is often used in radio frequency (RF) matching networks, RF amplifiers, circuit filters and oscillators. With its high current saturation, the SD7030-101-R inductor is ideal for applications in which current flows are above 2A. It is also suitable for band pass filters and high Q factor circuits. Additionally, the inductor can be used to provide better isolation on the input line of a circuit; this will further improve the signal-to-noise ratio and thus increase the reliability of the circuit.

The working principle of the SD7030-101-R fixed inductor is based on Faraday’s Law. This law states that when a current is passed through a conductor, a magnetic field is created in which the direction of the magnetic field is dependent on the direction of the current. This magnetic field produced will induce an opposing voltage drop across the coil, the magnitude of the voltage drop depending on the rate of the current change. This opposing voltage drop causes the inductance of the coil. As a result, the inductance of the coil is proportional to the current that passes through the coil.

In conclusion, SD7030-101-R fixed inductors are the perfect choice for high current radio frequency applications. They are highly stable, feature low losses, and can handle large current saturation. With its many advantageous features, the inductor is ideal for use in matching networks, RF amplifiers, and high Q circuits. Their working principle is based on the Faraday Law, creating an opposing voltage drop when a current is passed through the coil.
