Relevant Details:

Given the part number CD73-100MC, CD73 likely refers to the series and package size. The '100MC' most likely indicates an inductance value of 10µH (100 x 10^-6 H), with 'M' likely denoting a ±20% tolerance and 'C' being a Sumida specific identifier. However, you should consult the Sumida datasheet to confirm the specific inductance, saturation current, SRF (Self-Resonant Frequency), and other key electrical specifications.

Sumida's CD series inductors are widely used because they provide a good balance of performance, size, and cost. The shielded construction and robust design make them suitable for a variety of applications where EMI is a concern. Refer to the datasheet for detailed operating parameters and derating information to ensure optimal performance and reliability.
