SD7030-561-R

Generally, the SD7030-561-R fixed inductor is used in power supplies, converters, audio circuits, DC-DC circuits, and RF circuits. It is a low-pass filter and suppresses noises generated by pulse-width modulation of power drivers. It also works as an EMI filter, preventing unwanted electromagnetic interference. The SD7030-561-R fixed inductor has a rated current of 2.15A, an inductance of 560µH/550µH, a DC resistance of 0.096 ± 10%, and a Q value of 80.

The working principle of the SD7030-561-R fixed inductor is based on Faraday\'s law of induction, which states that an electric current induces a voltage across the inductor. When current passes through the coil, it creates a magnetic field, and when the current flows through the coil, the magnetic field changes. This, in turn, induces a voltage across the inductor, which is opposed to the change in current, and helps maintain the current. This process is called inductive reactance and is the basis of how the SD7030-561-R fixed inductor works.

The SD7030-561-R fixed inductor also has a self-resonant frequency of 230MHz and a maximum operating frequency of 68MHz. This makes it suitable for use in high-frequency applications such as RF transmission and digital communication. The inductor also has a high saturation current of 8.5A. This makes it ideal for use in power supplies, converters, and other applications that require high-current operation.

In addition, the SD7030-561-R fixed inductor has a maximum working temperature of 125°C, making it suitable for high temperature environments. The inductor also has a low DC resistance of 0.096 ± 10%, which means that it will not impede the current too much and result in higher power losses. The inductor also has a high Q-value (80), which indicates a good stability and improved performance in high frequency applications.
