Fixed inductors are widely used in electronic circuits for their ability to provide a steady flow of inductance in the presence of fluctuating voltage and currents. One of the most popular fixed inductors is the 70F103AI, which is a three-terminal component that provides high performance and multi-functional capabilities. This article will discuss the application fields and working principle of this inductor.

The 70F103AI is a three-terminal inductor with high current capacity and saturation current up to 5 Amps and 20 Amps, respectively. It is designed to be used in single-ended, fully-buffered, and fully-differential active filter circuits, as well as DC-DC converters, power amplifiers, and linear regulators. The 70F103AI has excellent high frequency characteristics with a frequency range of up to 1.8GHz. This inductor also offers low EMI emissions, low power consumption, wide output bandwidth, low distortion, and minimal phase shift.

In terms of working principle, the 70F103AI operates on the basic principles of electromagnetic induction. When a voltage is applied to the inductor, an electromagnetic field is created around the components’ three terminals. This field creates a current in the inductor as a result of its magnetic permeability. This current will flow through the terminals and will be affected by the inductance value, resistance, and capacitance of the component. As such, it is important to select the appropriate inductance value and frequency for the circuit, as this will affect the inductor’s total power loss.

In terms of its applications, the 70F103AI can be used in a variety of applications and circuits. It is especially suitable for high current-carrying applications such as switching power supplies, DC-DC converters, inductor-capacitor (LC) networks, as well as for RF switching applications. Moreover, the 70F103AI is also suitable for applications that require a wide bandwidth, low distortion, and high-frequency performance such as pointing systems, medical imaging systems, and imaging spectrometers.

In conclusion, the 70F103AI is a three-terminal inductor offering powerful and versatile performance across a range of applications and circuits. It provides a high current capacity and saturation current, excellent high frequency characteristics, low EMI emissions, low power consumption, wide output bandwidth, low distortion, and minimal phase shift. These features make it ideal for a variety of applications such as switching power supplies, DC-DC converters, anti-aliasing filters, and RF switching applications. The 70F103AI is thus a very valuable component for many applications.
