Procurement Notes

Verify the complete part number including suffixes to ensure correct termination and dielectric specifications. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Check for any specific handling requirements related to moisture sensitivity levels defined in the datasheet. Ensure compatibility with soldering profiles specified by the manufacturer to maintain electrical integrity during assembly processes.

Selection Notes

Select this component when space constraints require a 1206 footprint but superior EMI filtering performance is necessary. The three-terminal design offers better isolation than parallel two-terminal configurations. Consider the 300 mA current rating for power line applications. Verify that the X7R temperature characteristics align with the operational environment requirements of the target system design.

Part Context

This component belongs to the Knowles Syfer SMT EMI Filter series, specifically utilizing the E01/E07 type designation. These filters are engineered for high reliability in demanding environments. The 1206J series indicates a specific voltage and size code within the broader Syfer portfolio. This family emphasizes compact form factors combined with significant insertion loss capabilities for modern miniaturized electronics.

Replacement Considerations

Cross-reference with other 1206 three-terminal EMI filters from Knowles Syfer such as the 1206J0500223MXTE01 if higher voltage ratings are required. Verify pinout compatibility and physical dimensions before substituting with components from other manufacturers. Ensure equivalent insertion loss characteristics at target frequencies are maintained.
