1806Y1000822MXTE01

Overview

The Knowles Syfer 1806Y1000822MXTE01 is a three-terminal EMI filter capacitor in an 1806 (4516 metric) surface-mount package. It features an X7R dielectric with a capacitance of 8.2 nF and a tolerance of ±20%. The device is rated for 100 VDC 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 board flex sensitivity resilience

Applications

• Electromagnetic interference suppression in electronic circuits
• Power supply input filtering applications
• Signal line noise reduction in sensitive electronics

Procurement Notes

Verify the specific suffix TE01 against official datasheets to confirm the three-terminal EMI filter configuration and FlexiCap termination style. Ensure the X7R dielectric type aligns with circuit requirements, as it differs from C0G variants. Confirm packaging details such as reel quantities directly with the manufacturer or authorized distributors prior to ordering.

Selection Notes

Select this component when high capacitance values are required in a compact 1806 footprint for EMI suppression. The X7R dielectric offers higher volumetric efficiency than Class 1 alternatives but exhibits voltage coefficient characteristics. Evaluate thermal management needs given the 125°C maximum operating temperature limit.

Part Context

This part belongs to the Knowles Syfer FlexiCap series, which integrates flexible terminations to withstand mechanical stress on printed circuit boards. The 1806 case size provides a balance between current handling capability and space constraints in modern surface-mount assemblies.

Replacement Considerations

Direct substitutes include other 1806 three-terminal EMI filters with similar 8.2 nF X7R ratings. Verify terminal configuration and physical dimensions match before substitution.

FAQ

What is the primary function of the three-terminal design?

The three-terminal structure enables efficient shunting of common-mode noise to ground, providing superior electromagnetic interference filtering compared to standard two-terminal capacitors.

How does FlexiCap technology benefit this component?

FlexiCap technology incorporates a nickel barrier and flexible terminations to enhance resistance to cracking under board flex conditions, improving reliability in dynamic environments.
