1806Y0250272MJTE07

Overview

The Knowles Syfer 1806Y0250272MJTE07 is a multilayer ceramic capacitor (MLCC) designed as a three-terminal EMI filter. It features an 1806 (4516 metric) surface-mount package with X7R dielectric characteristics. The component has a capacitance of 2.7 nF, a DC voltage rating of 25 VDC, and a tolerance of ±20%. It utilizes FlexiCap technology with a nickel barrier for enhanced reliability.

Feature Summary

• Three-terminal architecture providing effective electromagnetic interference filtering
• FlexiCap termination system with nickel barrier to improve mechanical durability
• X7R dielectric material ensuring stable performance across operating temperatures

Applications

• High-frequency noise suppression in electronic circuits
• Power line filtering for sensitive signal paths
• EMI mitigation in compact surface-mount designs

Procurement Notes

Verify the complete part number including suffixes against official manufacturer documentation to ensure correct termination style and dielectric type. Confirm RoHS compliance status through current datasheets. Cross-reference Mouser or distributor specifications to validate packaging options such as reel quantities before ordering.

Selection Notes

Select this component when integrated EMI filtering is required within a standard MLCC footprint. The three-terminal design offers superior high-frequency attenuation compared to two-terminal capacitors. Ensure the circuit operates within the 25 VDC limit and that the X7R temperature coefficient aligns with thermal requirements.

Part Context

This component belongs to the Knowles Syfer FlexiCap series, which specializes in robust ceramic capacitors for demanding environments. The 1806 case size balances physical space constraints with electrical performance capabilities. It serves as a specialized passive component distinct from general-purpose capacitors due to its integrated filtering structure.

Replacement Considerations

Direct substitutes must match the 1806 footprint, 25V rating, 2.7nF capacitance, and three-terminal EMI filter topology. Verify compatibility of the nickel barrier termination and X7R dielectric class to maintain circuit integrity and mechanical stress resistance.
