1206Y0500104MXTE01

Overview

The Knowles Syfer 1206Y0500104MXTE01 is a Surface Mount Multilayer Ceramic Capacitor (MLCC) from the FlexiCap series. It features a capacitance of 0.1 µF with a ±20% tolerance and an X7R dielectric material. The component has a DC voltage rating of 50V and utilizes flexible termination technology to enhance mechanical reliability under board flexing conditions. It is housed in a standard 1206 (3216 metric) package, measuring 3.2 mm in length, 1.6 mm in width, and 1.6 mm in height. The device operates within a temperature range of -55°C to +125°C.

Feature Summary

• Flexible Soft Termination: Proprietary termination material accommodates significant board bending, reducing stress on the ceramic body compared to conventional rigid terminations.
• High Mechanical Reliability: Designed to withstand thermal cycling and mechanical shock without cracking, ensuring durability in demanding environments.
• AEC-Q200 Qualified: Meets automotive industry standards for passive components, suitable for high-reliability applications.

Applications

• Automotive electronics requiring AEC-Q200 compliance
• Circuit boards susceptible to mechanical flexing or warping
• General-purpose surface mount decoupling and filtering

Procurement Notes

Verify the specific suffix 'M' indicates ±20% tolerance and 'XTE01' denotes the terminal configuration and packaging format. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure PCB footprint matches the 1206 metric dimensions exactly to accommodate the flexible termination design properly.

Selection Notes

Select this component when mechanical flexibility is critical to prevent capacitor fracture during assembly or operation. The X7R dielectric offers stable capacitance over temperature, while the 50V rating suits low-voltage signal and power lines. Compare against rigid termination variants if board flexing is not a primary concern, noting that FlexiCap may have different handling requirements.

Part Context

This part belongs to the Knowles Syfer FlexiCap family, which specializes in MLCCs with enhanced mechanical robustness. The 1206Y prefix identifies the 1206 case size and general product line. This series addresses common failure modes in SMT assembly caused by board strain, making it a preferred choice for automotive and industrial sectors where reliability under stress is paramount.

Replacement Considerations

Direct substitutes must match the 1206 package, 0.1 µF capacitance, 50V rating, X7R dielectric, and flexible termination type. Verify that any alternative also holds AEC-Q200 qualification if used in automotive contexts. Generic MLCCs with rigid terminations are not equivalent due to differing mechanical performance characteristics.
