Frequently Asked Questions (FAQ)

Q: What makes CSD1013B-100M a suitable substitute for itself?

A: The CSD1013B-100M meets all electrical, mechanical, and compliance parameters required for direct substitution. It maintains identical inductance (10 µH), current rating (4.2 A), DC resistance (18 mOhm max), physical dimensions, and regulatory certifications (RoHS3, REACH unaffected).

Q: Are there any differences between the main part and substitute part listed?

A: No. The main part and substitute part are identical in all specified parameters. Both are CSD1013B-100M manufactured by CODACA with the same electrical characteristics, physical dimensions, and compliance status.

Q: What parameters are critical for mechanical compatibility?

A: The 4-SMD package configuration, dimensions of 0.512" L x 0.413" W (13.00 mm x 10.50 mm), and maximum seated height of 0.413" (10.50 mm) are critical for PCB footprint compatibility. Any deviation in these parameters will result in assembly or clearance issues.

Q: What is the significance of the 18 mOhm maximum DC resistance specification?

A: DC resistance directly impacts thermal performance and power dissipation in the inductor. The 18 mOhm maximum specification ensures that resistive losses remain within acceptable limits for the 4.2 A current rating, maintaining efficiency and preventing excessive heat generation in the application circuit.

Q: Why is the saturation current (Isat) of 7.1 A important?

A: Saturation current defines the maximum current level before the ferrite core saturates and inductance degrades. The 7.1 A saturation rating provides a safety margin above the 4.2 A continuous current rating, protecting the inductor from performance degradation during transient overcurrent conditions.

Q: What does RoHS3 compliance mean for this inductor?

A: RoHS3 compliance certifies that the CSD1013B-100M meets the Restriction of Hazardous Substances Directive, limiting the use of specific hazardous materials including lead, cadmium, mercury, and certain flame retardants. This compliance is required for products sold in the European Union and many other regulated markets.

Q: Is special handling required for this inductor during storage or assembly?

A: No. The Moisture Sensitivity Level (MSL) of 1 (Unlimited) indicates that the CSD1013B-100M does not require special moisture control measures. Standard handling and storage conditions are acceptable.

Q: Can this inductor be used in applications requiring temperatures below -40°C or above 125°C?

A: No. The operating temperature range is specified as -40°C ~ 125°C. Applications requiring operation outside this range require alternative components with extended temperature specifications.

Q: What is the significance of the shielded construction?

A: Shielded construction reduces electromagnetic interference (EMI) radiation and susceptibility by containing the magnetic field within the component. This is critical in high-frequency switching applications and noise-sensitive circuits to prevent coupling with adjacent components and traces.

Q: Why is the ferrite core material specified?

A: Ferrite core material provides high permeability and low losses at the operating frequency (1 kHz test frequency), enabling compact size while maintaining the required inductance value. Ferrite also offers stable inductance across the -40°C ~ 125°C temperature range.
