1206Y1000682MJTE03

Overview

The Knowles Syfer 1206Y1000682MJTE03 is a three-terminal EMI filter capacitor housed in a 1206 (3216 metric) surface-mount package. It features an X7R dielectric with a capacitance of 82 nF and a tolerance of ±20%. The component is rated for a DC voltage of 25 V and operates within a temperature range of -55°C to +125°C. It utilizes FlexiCap technology with a nickel barrier for enhanced mechanical reliability.

Feature Summary

• Three-terminal architecture designed for effective electromagnetic interference filtering
• FlexiCap construction with nickel barrier to improve resistance to board flexure stress
• X7R dielectric material providing stable performance across the specified operating temperature range

Applications

• High-density circuit boards requiring robust EMI suppression
• Applications sensitive to mechanical stress from PCB bending
• Power supply input/output filtering stages

Procurement Notes

Verify the specific voltage rating during procurement, as datasheet references indicate both 25 VDC and 100 VDC variants exist within this part family. Confirm the exact capacitance value required for the design, as naming conventions may vary between 6.8 nF and 82 nF versions. Ensure the supplier provides official documentation matching the MJTE03 suffix to guarantee the correct three-terminal configuration and terminal plating specifications.

Selection Notes

Select this component when high-frequency noise attenuation is critical alongside mechanical durability. The three-terminal design offers superior high-frequency performance compared to standard two-terminal capacitors. Consider the FlexiCap feature if the assembly process involves significant board flexing or if the application demands higher reliability under mechanical strain. Verify that the 25 VDC rating meets the circuit's maximum operating voltage requirements.

Part Context

This component belongs to the Knowles Syfer FlexiCap series, which specializes in high-reliability multilayer ceramic capacitors. The series integrates flexible terminations and nickel barriers to mitigate cracking risks. As a three-terminal device, it functions as an integrated EMI filter, combining capacitance with low-inductance grounding paths for enhanced signal integrity in compact footprints.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source data. Evaluate other three-terminal EMI filters from the same manufacturer with matching 1206 dimensions and compatible voltage ratings.
