1206J0500223MJTE07

Overview

The Knowles Syfer 1206J0500223MJTE07 is a surface-mount multilayer ceramic capacitor (MLCC) designed as a three-terminal EMI filter. It features a capacitance of 22 nF with a tolerance of ±20%, rated for a DC voltage of 50 V. The component utilizes X7R dielectric material and operates within a temperature range of -55°C to +125°C. Housed in a standard 1206 (3216 metric) package, it incorporates a nickel barrier structure with 100% tin termination plating to ensure reliable solderability and environmental resistance.

Feature Summary

• Three-terminal architecture provides enhanced electromagnetic interference filtering performance compared to standard two-terminal capacitors.
• Nickel barrier construction protects the internal electrodes from corrosion and ensures robust mechanical integrity during thermal cycling.
• X7R dielectric material offers stable capacitance characteristics across the specified industrial operating temperature range.

Applications

• Electromagnetic interference suppression in high-density electronic circuits
• Power supply input/output filtering for sensitive digital logic
• Signal line protection in automotive and industrial control systems

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm terminal configuration and packaging details. Ensure that the selected variant matches the required nickel barrier specification and 100% tin plating for compatibility with intended assembly processes. Cross-reference the part number with official distributor catalogs to confirm availability status and lead times prior to finalizing procurement plans.

Selection Notes

Select this component when superior common-mode noise attenuation is required in space-constrained designs. The three-terminal design allows for lower effective series inductance, making it suitable for high-frequency applications. Consider the X7R dielectric stability and 50V rating to ensure adequate margin for operational voltage spikes and temperature variations in the target circuit environment.

Part Context

This component belongs to the Knowles Syfer FlexiCap/Nickel Barrier series of MLCCs. These parts are engineered for high reliability in demanding environments, combining the electrical benefits of ceramic capacitors with the structural advantages of specialized termination technologies. The series is widely recognized for its durability in automotive and industrial sectors where long-term performance under stress is critical.

Replacement Considerations

Direct substitutes must match the 1206 footprint, 50V rating, 22nF capacitance, and three-terminal EMI filter topology. Verify that alternative components also feature X7R dielectric and compatible termination materials to maintain mechanical and electrical equivalence in the assembly process.
