Specifications

The SCDS125T-121M-N has an inductance of 120μH with a ±20% tolerance. It is designed for surface mount assembly. The operating temperature range is typically -40°C to +125°C. The shielded construction minimizes EMI, allowing it to be used in close proximity to other sensitive components. The ferrite core material provides high permeability and low core losses. This inductor is often used in step-up and step-down DC-DC converters to store and release energy efficiently. The saturation current is high, allowing for reliable operation under peak load conditions. The physical dimensions of the SCDS125T package allow for a good balance between size and performance, suitable for various applications.

Yageo's SCDS series provides many inductors with a range of inductance values, current ratings, and sizes. The SCDS125T-121M-N offers a good combination of inductance value and current carrying capabilities.
