1206Y1000123MXTE07

Overview

The Knowles Syfer 1206Y1000123MXTE07 is a surface-mount multilayer ceramic capacitor (MLCC) designed for high-reliability applications. It features a 12 nF capacitance with a ±20% tolerance, rated at 100 VDC. The component utilizes C0G/NP0 dielectric material, ensuring stable performance across a temperature range of -55°C to +125°C. Housed in a standard 1206 (3216 metric) package, it incorporates flexible end terminations and a nickel barrier structure to enhance mechanical durability against board flexing.

Feature Summary

• Flexible end terminations reduce stress from PCB bending
• Nickel barrier construction improves solder joint reliability
• C0G/NP0 dielectric provides minimal capacitance variation over temperature

Applications

• Automotive electronics requiring AEC-Q200 compliance
• Board-flex sensitive circuit designs
• High-frequency signal coupling and decoupling

Procurement Notes

Verify the specific suffix MXTE07 against official Knowles Syfer documentation to confirm terminal composition and barrier layer specifications. Ensure procurement channels provide valid traceability records. Confirm that the C0G dielectric classification matches the design requirements for low-loss applications. Validate RoHS compliance status through current manufacturer declarations before integration into production.

Selection Notes

Select this component when board flex resistance is critical due to its soft termination technology. The C0G dielectric is suitable for precision timing or filtering where stability is paramount. The 1206 footprint offers a balance between capacitance density and power handling. Consider the nickel barrier for enhanced solderability in harsh environments compared to standard tin-only terminations.

Part Context

This part belongs to the FlexiCap series, engineered specifically for automotive and industrial sectors. It addresses common failure modes associated with mechanical stress on rigid MLCCs. The 1206Y prefix indicates the case size and voltage rating family within the Knowles Syfer portfolio.

Replacement Considerations

Direct substitutes must match the 1206 case size, 12 nF value, C0G dielectric, and flexible termination type. Verify equivalent nickel barrier specifications if solder reliability is a primary concern.
