1206Y1000272MJTE03

Overview

The Knowles Syfer 1206Y1000272MJTE03 is a surface-mount multilayer ceramic capacitor (MLCC) housed in a 1206 (3216 metric) package. It features an X7R dielectric with a capacitance of 2700 pF and a tolerance of ±20%. The component has a DC voltage rating of 100 VDC and operates within a temperature range of -55°C to +125°C. It incorporates FlexiCap termination technology with a nickel barrier for enhanced reliability.

Feature Summary

• FlexiCap termination technology designed to reduce mechanical cracking caused by board flexure
• Nickel barrier electrode structure providing improved solderability and corrosion resistance
• X7R dielectric material ensuring stable capacitance performance across the operating temperature range

Applications

• Automotive electronics requiring AEC-Q200 qualification
• Applications subject to mechanical stress or board flexure
• General-purpose decoupling and bypass circuits

Procurement Notes

Verify the specific suffix JTE03 against official datasheets to confirm the presence of the nickel barrier and FlexiCap termination, as these are critical for automotive-grade reliability. Ensure the supplier provides traceability documentation consistent with AEC-Q200 standards. Cross-reference the manufacturer part number directly with Knowles Syfer to avoid confusion with similar X7R variants lacking the specialized termination structure.

Selection Notes

Select this component when high reliability under mechanical stress is required in automotive environments. The X7R dielectric offers a balance of capacitance density and stability suitable for general filtering. The 1206 footprint allows for higher capacitance values compared to smaller packages while maintaining standard mounting compatibility. Verify that the 100V rating meets the circuit's maximum operating voltage requirements.
