1206Y1000392MJTE07

Overview

The Knowles Syfer 1206Y1000392MJTE07 is a 3-terminal EMI filter capacitor in a 1206 (3216 metric) surface-mount package. It features a 3900 pF capacitance with ±20% tolerance and a 100 VDC rated voltage. The component utilizes C0G/NP0 dielectric material for stable performance across its operating temperature range of -55°C to +125°C. It incorporates a FlexiCap design with a nickel barrier and tin-plated terminals to enhance mechanical reliability.

Feature Summary

• Integrated 3-terminal architecture provides effective electromagnetic interference filtering within a compact footprint.
• FlexiCap construction with nickel barrier reduces stress on termination pads during board flexing.
• C0G/NP0 dielectric ensures minimal capacitance variation over temperature and voltage changes.

Applications

• High-reliability electronic assemblies requiring EMI suppression
• Board-flex sensitive circuit designs
• Automotive electronics applications

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm terminal plating and barrier specifications. Ensure compatibility with automated pick-and-place equipment regarding the 1206 package dimensions. Confirm RoHS compliance status through current datasheets before integration into regulated products.

Selection Notes

Select this component when both EMI filtering and mechanical durability are required in space-constrained layouts. The 3-terminal design offers superior high-frequency attenuation compared to standard 2-terminal capacitors. Evaluate board flex requirements to determine if the FlexiCap nickel barrier feature is necessary for the target application environment.
