1206J0500222MJTE07

Overview

The Knowles Syfer 1206J0500222MJTE07 is a three-terminal EMI filter capacitor in a 1206 (3216 metric) surface-mount package. It features an X7R dielectric with a capacitance of 2.2 nF and a tolerance of ±20%. The device has a DC voltage rating of 50 V and operates within a temperature range of -55°C to +125°C. It utilizes a nickel barrier electrode structure with 100% tin terminations, designed for high-frequency noise suppression.

Feature Summary

• Three-terminal architecture provides enhanced electromagnetic interference filtering performance compared to standard two-terminal capacitors.
• Nickel barrier electrode construction ensures reliable solderability and mechanical stability during surface mount assembly.
• X7R dielectric material offers stable capacitance characteristics across the specified industrial operating temperature range.

Applications

• High-frequency noise suppression in sensitive signal lines
• Electromagnetic interference filtering in communication equipment
• Power line conditioning in compact electronic modules

Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm RoHS compliance status using official manufacturer documentation. Ensure storage conditions meet moisture sensitivity level requirements prior to reflow soldering. Validate terminal integrity against shipping damage indicators.

Selection Notes

Select this component when three-terminal EMI filtering is required in a 1206 footprint. The X7R dielectric suits applications needing moderate capacitance stability over temperature. Verify that the 50V rating exceeds circuit peak voltages. Consider the nickel barrier termination for compatibility with standard lead-free soldering processes.

Part Context
