1806Y0250823MJTE07

Overview

The Knowles Syfer 1806Y0250823MJTE07 is a three-terminal EMI filter capacitor in an 1806 (4516 metric) surface-mount package. It features a capacitance of 82 nF with a tolerance of ±20% and a rated DC voltage of 25V. The dielectric material is X7R, providing stability across a temperature range of -55°C to +125°C. This component 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 flexing stress
• X7R dielectric material ensuring stable performance within specified temperature limits

Applications

• High-reliability electronic assemblies requiring EMI suppression
• Circuit boards sensitive to mechanical stress or flexing
• Power supply input/output filtering stages

Procurement Notes

Verify the specific suffix codes against official datasheets to confirm terminal configuration and termination materials. Ensure compatibility with PCB pad layouts designed for three-terminal components. Confirm RoHS compliance status through current manufacturer documentation before integration into regulated products.

Selection Notes

Select this component when high-frequency noise attenuation is required alongside mechanical durability. The three-terminal design offers superior high-frequency performance compared to standard two-terminal capacitors. Evaluate thermal requirements to ensure operation remains within the -55°C to +125°C range defined by the X7R dielectric characteristics.

Part Context

This part belongs to the Knowles Syfer FlexiCap series, which specializes in multilayer ceramic capacitors engineered for harsh environments. The series emphasizes mechanical robustness through flexible terminations and nickel barriers, addressing common failure modes associated with board warping and thermal cycling in high-reliability applications.

Replacement Considerations

Direct substitutes must match the 1806 footprint, 82nF capacitance, 25V rating, and three-terminal EMI filter topology. Verify that alternative parts support X7R dielectric properties and FlexiCap-style mechanical protection if board flex resistance is critical.
