1806J0500221MCTE01

Overview

The Knowles Syfer 1806J0500221MCTE01 is a surface-mount feed-through capacitor designed for EMI suppression. It features a capacitance of 220 pF with a tolerance of ±20%. The component operates at a DC voltage rating of 50 V and supports a maximum current of 300 mA. It utilizes C0G/NP0 dielectric material and is housed in an 1806 (4516 metric) package. The device includes nickel barrier terminations and functions as a three-terminal filter.

Feature Summary

• Three-terminal feed-through architecture for effective electromagnetic interference filtering
• Nickel barrier termination structure ensuring reliable surface mount integration
• C0G/NP0 dielectric composition providing stable capacitance characteristics across operating temperatures

Applications

• High-frequency signal line noise suppression
• Power distribution network filtering in compact electronics
• EMI mitigation in RF communication modules

Procurement Notes

Verify the specific ordering suffix to confirm terminal configuration and packaging type, as variations exist within the series. Ensure the selected variant matches the required current rating and voltage derating for the target application environment. Cross-reference the datasheet for precise mechanical dimensions to validate PCB footprint compatibility before finalizing procurement orders.

Selection Notes

Select this component when space-constrained designs require high-performance EMI filtering without compromising signal integrity. The 1806 package offers a balance between capacitance density and thermal management. Consider the 300 mA current handling capability against peak load requirements. The nickel barrier termination is suitable for standard reflow soldering processes commonly used in modern assembly lines.

Part Context

This part belongs to the Knowles Syfer E01 series of surface-mount EMI filters. These components are engineered for high-reliability applications requiring robust noise suppression in small form factors. The series is characterized by its consistent performance under varying thermal conditions and its compatibility with automated placement equipment.

Replacement Considerations

Direct substitutes must match the 1806 package, 50V rating, and 220pF capacitance. Verify that alternative parts support the same 300 mA current rating and utilize compatible termination materials for equivalent soldering reliability.
