1806J0250123MJTE07

Overview

The Knowles Syfer 1806J0250123MJTE07 is a three-terminal multilayer ceramic capacitor (MLCC) designed as an EMI filter. It features a 1206 package size with a capacitance of 12 nF and a DC voltage rating of 25 VDC. The component utilizes X7R dielectric material with a tolerance of ±20%. It incorporates a nickel barrier structure for enhanced reliability and is terminated with 100% tin. This device is classified as a Class 1 high-reliability MLCC suitable for surface mount applications.

Feature Summary

• Three-terminal architecture providing effective electromagnetic interference filtering
• Nickel barrier construction ensuring robust performance in demanding environments
• X7R dielectric material offering stable capacitance characteristics across temperature ranges

Applications

• High-frequency noise suppression in electronic circuits
• Power supply input/output filtering stages
• Signal line protection against electromagnetic interference

Procurement Notes

Verify the complete part number including suffixes to ensure correct termination and barrier specifications. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Check for specific handling requirements related to the nickel barrier structure during assembly processes.

Selection Notes

Select this component when three-terminal EMI filtering is required in a compact 1206 footprint. Consider the X7R dielectric properties for general-purpose applications where moderate capacitance stability is sufficient. Ensure the 25V rating meets the circuit's maximum operating voltage requirements.

Part Context

This component belongs to the Knowles Syfer high-reliability MLCC family, specifically engineered for EMI suppression. The J series denotes standard commercial grade components with nickel barrier technology. It serves as a specialized passive component distinct from standard two-terminal capacitors by integrating filtering functionality directly into the package structure.

Replacement Considerations

Direct substitutes must match the 1206 package, 12nF capacitance, 25V rating, and three-terminal EMI filter configuration. Verify compatibility of the nickel barrier and X7R dielectric characteristics. Cross-reference with other manufacturers' three-terminal EMI filter offerings in the same form factor.
