1806J0500223MJTE07

Overview

The Knowles Syfer 1806J0500223MJTE07 is a surface-mount multilayer ceramic capacitor (MLCC) designed for EMI filtering applications. It features a 1806 (4516 metric) package size with a capacitance of 22 nF and a voltage rating of 50 VDC. The component utilizes X7R dielectric material, providing a capacitance tolerance of ±20%. It employs a three-terminal architecture with nickel barrier terminations to enhance signal integrity and suppress electromagnetic interference in high-frequency circuits.

Feature Summary

• Three-terminal EMI filter architecture for effective noise suppression
• Nickel barrier termination technology for improved reliability
• X7R temperature stable ceramic dielectric construction

Applications

• Electromagnetic interference (EMI) filtering in electronic circuits
• Signal integrity enhancement in high-speed data lines
• Power supply decoupling and noise reduction

Procurement Notes

Verify the complete part number including suffixes against official manufacturer documentation to ensure correct termination and packaging specifications. Confirm RoHS compliance status through current datasheets. Cross-reference Mouser or distributor identifiers to validate authenticity and avoid counterfeit components during sourcing.

Selection Notes

Select this component when a 1806 footprint is required for EMI suppression with 22 nF capacitance at 50 VDC. Ensure the design accommodates the physical dimensions of the three-terminal structure. Verify that the X7R dielectric characteristics align with the operating temperature range requirements of the target application environment.

Part Context

This component belongs to the Knowles Syfer MLCC series, specifically engineered for surface mount technology. It falls under the category of ceramic capacitors designed for passive filtering. The 1806 case size offers a balance between capacitance density and physical space constraints in modern PCB layouts.

Replacement Considerations

Direct substitutes must match the 1806 package, 22 nF capacitance, 50 VDC rating, and three-terminal EMI filter topology. Verify compatibility of nickel barrier terminations and X7R dielectric properties before integration.
