1206J2000682MJTE03

Overview

The Knowles Syfer 1206J2000682MJTE03 is a surface-mount X2Y capacitor featuring a 6.8 nF capacitance with ±20% tolerance and a 200 VDC voltage rating. Utilizing X7R dielectric, it operates within a temperature range of -55°C to +125°C. The component employs a nickel barrier with 100% tin termination for soldering. It is housed in a standard 1206 (3216 metric) package, designed for high-reliability EMI suppression applications.

Feature Summary

• X2Y architecture providing simultaneous common-mode and differential-mode noise filtering
• Nickel barrier termination structure ensuring robust solder joint integrity
• Compact 1206 footprint optimized for dense surface-mount layouts

Applications

• High-frequency EMI suppression in sensitive electronic circuits
• Power line filtering for DC-DC converters
• Signal line protection in communication interfaces

Procurement Notes

Verify the specific ordering suffix 'MJTE03' against the manufacturer's current datasheet to confirm termination material and packaging configuration. Ensure compatibility with automated pick-and-place equipment regarding the 1206 reel specifications. Cross-reference RoHS compliance status with the latest environmental declaration before final procurement approval.

Selection Notes

Select this component when dual-mode noise attenuation is required in a minimal footprint. The X7R dielectric offers stable performance across the specified industrial temperature range. Consider the 200V rating relative to peak transient voltages in the target circuit to ensure adequate margin without over-specifying voltage capability unnecessarily.

Part Context

This part belongs to the Knowles Syfer X2Y family, which integrates three terminals into a single monolithic structure. Unlike discrete capacitor networks, this design reduces parasitic inductance and saves board space. It serves as a direct replacement for traditional two-capacitor EMI filter configurations in high-density PCB designs.

Replacement Considerations
