It offers a capacitance of 0.15 µF with a tolerance of ±20% and a rated DC voltage of 100V. Designed for high-reliability applications, this component utilizes the FlexiCap™ technology to enhance mechanical robustness against board flexing stresses. The device meets AEC-Q200 automotive qualification standards and operates within a temperature range of -55°C to +125°C.

Feature Summary

• FlexiCap™ soft termination design provides enhanced resistance to mechanical stress during board flexing.
• AEC-Q200 qualified for use in demanding automotive electronic environments.
• X7R dielectric material ensures stable capacitance performance across a wide operating temperature range.

Applications

• Automotive electronics requiring board-flex sensitive components
• High-reliability surface mount circuits
• General purpose decoupling and filtering in automotive grade systems

Procurement Notes

Verify the complete part number including the E03 suffix when sourcing, as it denotes specific termination or barrier materials. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure storage conditions align with moisture sensitivity level requirements to prevent damage during soldering processes.

Selection Notes

Select this component for designs prioritizing mechanical durability over standard MLCCs due to its soft termination structure. The X7R dielectric provides higher volumetric efficiency compared to Class 1 ceramics but exhibits greater capacitance variation with voltage. Verify that the 100V rating sufficiently exceeds peak circuit voltages to maintain reliability under dynamic load conditions.

Part Context

This part belongs to the Knowles Syfer 1812Y series, which focuses on high-reliability solutions for the automotive sector. The series integrates specialized termination technologies to address common failure modes associated with rigid terminations in flexible printed circuit boards. It represents a specialized subset of general-purpose MLCCs tailored for stringent quality and longevity standards.

Replacement Considerations

Direct substitutes must match the 1812 footprint, 100V rating, 0.15µF value, and X7R dielectric. Crucially, replacements should also feature soft termination or FlexiCap-like technology if board flex resistance is required. Standard rigid-termination capacitors may fail prematurely in identical mechanical environments despite matching electrical specifications.

FAQ

What does the E03 suffix indicate in the part number?

The E03 suffix typically specifies the terminal material composition and barrier layer configuration, such as nickel barrier with tin plating, ensuring compatibility with specific soldering profiles and corrosion resistance requirements.

Is this capacitor suitable for high-voltage pulse applications?

While rated for 100V DC, X7R dielectrics exhibit significant capacitance reduction under applied DC bias. For high-voltage pulse applications, verify the actual capacitance at the operating voltage using the manufacturer's derating curves to ensure sufficient charge storage.
