ASPI-0615FS-4R7M-T2

Fixed inductors are passive electrical components used to store energy in the form of magnetic fields. The ASPI-0615FS-4R7M-T2 is a fixed inductor that is rated for power up to 1 watt and is suitable for high frequency applications. It has a metal alloy core material with 4R7M-T2 tape-and-reel packaging. It has a high saturation current, low inrush current, and low residual current. This makes it ideal for use in high-efficiency power supplies in applications such as cell phone power amplifiers and LED drivers.

Application Field

The ASPI-0615FS-4R7M-T2 is ideal for use in applications requiring high frequency power conversion or signal processing. It is typically used in power applications such as power management, switching power supplies, charge pump circuits, Class D amplifiers and LED drivers. It can also be used in signal processing, such as in TV and radio tuners. Additionally, it is suitable for use in digital and analog circuits for applications such as switching regulators or stabilizers.

Working Principle

The ASPI-0615FS-4R7M-T2 works by storing energy in the form of a magnetic field. When an alternating current is applied to its terminals, it creates a current loop inside the core which creates a magnetic field. This field remains relatively constant over time, regardless of the waveform of the alternating current. As the current waveform changes, the magnetic field also changes, inducing a voltage in the inductor’s terminals. This voltage, also known as the self-inductance voltage of the inductor, is proportional to the rate of change of the current waveform.

The aspect ratio of the ASPI-0615FS-4R7M-T2 (4R7M-T2) is one of the key indicators of its performance. The aspect ratio is the ratio of the radial thickness of the core material to its axial length. This determines the strength of the magnetic field and thus the inductance of the inductor. A low aspect ratio results in a larger inductance and a higher inductance will result in a larger voltage across the terminals.

Due to its high saturation current, low inrush current, and low residual current capabilities, the ASPI-0615FS-4R7M-T2 is an ideal choice for high frequency applications and high efficiency power supplies. It is also highly reliable, making it suitable for long-term use in a variety of industrial, automotive, and consumer applications.
