1806Y0250224MJTE07

Overview

The Knowles Syfer 1806Y0250224MJTE07 is a surface-mount feed-through capacitor designed for high-frequency noise suppression. It features a capacitance of 0.22 µF with a tolerance of ±20%, rated for a DC voltage of 25V and a continuous current of 2A. The component utilizes an X7R dielectric material and is housed in an 1806 (4516 metric) package. It employs a three-pad configuration to facilitate efficient PCB layout while maintaining signal integrity.

Feature Summary

• Integrated feed-through architecture providing effective electromagnetic interference filtering within a compact footprint.
• High current handling capability suitable for power line applications requiring robust performance under load.
• Three-terminal pad design ensures stable mechanical mounting and optimized electrical connectivity.

Applications

• Electromagnetic interference filtering in high-density electronic assemblies
• Power supply input stages requiring noise suppression
• Signal conditioning circuits demanding high-current tolerance

Procurement Notes

Verify the specific revision level and packaging details directly with the manufacturer or authorized distributor before ordering. Confirm that the three-pad footprint matches your PCB design constraints. Ensure compliance with RoHS directives and check for any specific handling requirements related to the nickel barrier construction.

Selection Notes

Select this component when space constraints preclude larger filter capacitors but high current capacity is required. The 1806 package offers a balance between size and power handling. Consider the X7R temperature characteristics if operating in varying thermal environments. Validate impedance specifications against target frequency ranges to ensure adequate attenuation.

Part Context

This part belongs to the Knowles Syfer FlexiCap series, which specializes in flexible termination technologies to enhance reliability under mechanical stress. The 1806Y series indicates a standard SMD form factor optimized for automated assembly processes. It serves as a specialized solution for EMI mitigation where traditional two-terminal capacitors may lack sufficient current ratings or physical stability.

Replacement Considerations

Direct substitutes must match the 0.22 µF capacitance, 25V rating, 2A current capacity, and 1806 footprint. Verify that alternative feed-through capacitors support the same three-pad configuration. Ensure compatibility with X7R dielectric properties if temperature stability is critical. Cross-reference pinout definitions to prevent installation errors.
