• Surface mount wirewound construction with metal composite core
• Shielded configuration
• Nonstandard package dimensions: 0.886" L x 0.866" W (22.50mm x 22.00mm)
• Maximum seated height of 0.488" (12.40mm)

Performance & Compliance:

• Operating temperature range of -50°C to 150°C
• AEC-Q200 automotive qualification

Engineering Selection Recommendations

The CSBL2212-220M is an active production component with full AEC-Q200 automotive qualification and ROHS3 compliance. The part is suitable for applications requiring high reliability and regulatory compliance in automotive and industrial environments.

When selecting equivalent or substitute components, the following engineering criteria apply:

Product Status Consideration: The main part maintains active production status with 892 pieces in current inventory. Substitute parts must also maintain active production status to ensure long-term availability and supply chain continuity.

Compliance & Certification: All substitute parts must retain AEC-Q200 automotive qualification and ROHS3 compliance. These certifications are mandatory for applications requiring automotive-grade reliability and environmental compliance.

Electrical Performance: Substitute parts must deliver identical electrical performance across all specified parameters: 22 µH inductance, 15 A current rating, 21 A saturation current, and 8.25 mOhm maximum DC resistance. Deviations in any electrical specification result in functional incompatibility.

Mechanical Compatibility: The nonstandard package dimensions (22.50mm x 22.00mm footprint with 12.40mm maximum height) are critical for PCB layout and thermal management. Substitute parts must match these dimensions exactly to ensure mechanical fit and thermal performance.

Environmental Performance: The operating temperature range of -50°C to 150°C and moisture sensitivity level 1 (unlimited) must be maintained in all substitute selections to ensure performance across the full application temperature envelope.

Frequently Asked Questions (FAQ)

Q: What makes the CSBL2212-220M suitable for high current applications?

A: The CSBL2212-220M is rated for 15 A continuous current with a saturation current of 21 A. The metal composite core construction and flat wire design enable efficient current handling while maintaining a low DC resistance of 8.25 mOhm maximum. The shielded wirewound configuration reduces electromagnetic interference in high current switching applications.

Q: Are there alternative inductance values available in the CSBL2212 series?

A: The provided data specifies only the CSBL2212-220M with 22 µH inductance. Alternative inductance values within the CSBL2212 series are not included in this equivalence reference. Component selection for different inductance requirements requires separate technical documentation.

Q: What is the significance of the ±20% inductance tolerance?

A: The ±20% tolerance indicates the acceptable range of inductance variation from the nominal 22 µH value. This tolerance is typical for wirewound inductors with metal composite cores. Circuit designs must account for this tolerance range in inductance calculations and performance simulations.

Q: Why is the nonstandard package dimension critical for substitution?

A: The nonstandard 22.50mm x 22.00mm footprint and 12.40mm maximum height are specific to this component design. PCB layouts are designed around these exact dimensions. Substitute parts with different package dimensions will not fit the existing PCB footprint and require circuit board redesign.

Q: What does AEC-Q200 qualification mean for this inductor?

A: AEC-Q200 is an automotive electronics council qualification standard for passive components. This certification confirms the CSBL2212-220M meets automotive industry reliability, performance, and environmental stress testing requirements. Components with AEC-Q200 qualification are approved for use in automotive applications.

Q: Is the CSBL2212-220M suitable for high frequency switching applications?

A: The inductance test frequency is specified at 100 kHz. The high Q value and flat wire construction indicate optimized performance for switching applications in this frequency range. Applications requiring operation at significantly different frequencies require separate frequency response analysis.

Q: What is the difference between current rating and saturation current?

A: The current rating of 15 A is the continuous operating current limit. The saturation current (Isat) of 21 A is the current level at which the inductor's inductance begins to degrade due to core saturation. Operating above the saturation current results in reduced inductance and increased losses.

Q: Does ROHS3 compliance affect component performance?

A: ROHS3 compliance indicates the component is manufactured without restricted hazardous substances. This compliance status does not alter electrical or mechanical performance characteristics. It confirms environmental and regulatory compliance for applications subject to ROHS directives.

Q: What is the moisture sensitivity level (MSL) 1 rating?

A: MSL 1 (Unlimited) indicates the component has unlimited shelf life and does not require special moisture control during storage or handling. This is the least restrictive moisture sensitivity classification and simplifies component logistics and inventory management.

Q: Can the CSBL2212-220M be used in applications with operating temperatures below -50°C or above 150°C?

A: The specified operating temperature range is -50°C to 150°C. Operation outside this range is not supported by the component specifications. Applications requiring extended temperature ranges require alternative component selection with appropriate temperature ratings.
