Overview
The Knowles Syfer 1206Y2000472MJTE03 is a surface-mount multilayer ceramic capacitor (MLCC) designed for high-reliability applications. It features a 1206 (3216 metric) case size with a capacitance of 4700 pF and a DC voltage rating of 200 V. The component utilizes X7R dielectric material with a tolerance of ±20%. It incorporates FlexiCap technology with a nickel barrier to enhance mechanical robustness against board flexing. This part is AEC-Q200 qualified, ensuring suitability for automotive environments.
Feature Summary
- FlexiCap flexible termination design with nickel barrier for enhanced board flex resistance
- AEC-Q200 qualification for automotive reliability standards
- X7R dielectric providing stable performance across operating temperatures
Applications
- Automotive electronics requiring board flex sensitivity mitigation
- High-voltage decoupling in automotive circuits
- EMI filtering applications utilizing 3-terminal architecture
Procurement Notes
Verify the specific suffix codes against official Knowles Syfer documentation to confirm terminal composition and barrier materials. Ensure the procurement channel provides valid traceability records for AEC-Q200 compliance. Confirm that the reel packaging matches the required quantity specifications for your manufacturing process. Cross-reference the datasheet revision date to ensure compatibility with current design constraints.
Selection Notes
Select this component when board flex resistance is critical in automotive or industrial settings. The 1206 footprint offers a balance between capacitance density and mechanical strength. Consider the X7R temperature characteristics for stability requirements. Verify that the 200V rating aligns with the circuit's peak voltage stresses. Evaluate the nickel barrier termination for solderability and long-term reliability in harsh environments.
Part Context
This component belongs to the Knowles Syfer 1206Y series of high-reliability MLCCs. The series is engineered specifically for automotive and aerospace markets where mechanical stress and voltage stability are paramount. The Y-series typically denotes specialized termination technologies like FlexiCap, distinguishing it from standard commercial-grade capacitors in terms of durability and failure rate performance.
Replacement Considerations
Direct substitutes must match the 1206 package, 200V rating, 4700pF capacitance, and X7R dielectric. Verify that any replacement also includes FlexiCap/Nickel Barrier technology and holds AEC-Q200 qualification. Generic X7R capacitors without flexible terminations may fail under board flex conditions.
