Technical Specifications:

The SCD0403T-220M-S inductor utilizes a ferrite core to achieve a balance between inductance, saturation current, and core loss. It is designed to operate within a temperature range of -40°C to +125°C. Typical rated current is approximately 0.7A, with a saturation current around 0.9A. The DC resistance (DCR) is relatively low, generally around 0.2 ohms, minimizing power dissipation. The “S” suffix indicates standard packaging compatible with automated assembly processes.

This inductor is often used in applications that demand a small and efficient power solution, providing a good balance between size, performance, and cost. Its shielded construction makes it suitable for sensitive applications where EMI is a concern.
