1206J0500124MXTE07

Overview

The Knowles Syfer 1206J0500124MXTE07 is a multilayer ceramic capacitor (MLCC) designed as a surface-mount EMI filter. It features a 1206 package size with a capacitance of 120 nF and a voltage rating of 50 VDC. The dielectric material is X7R, providing a tolerance of ±20%. This component utilizes a three-terminal architecture with a nickel barrier and 100% tin termination to enhance electromagnetic interference suppression capabilities.

Feature Summary

• Three-terminal structure for effective common-mode noise attenuation
• Nickel barrier construction with 100% tin terminations for reliable soldering
• X7R dielectric material suitable for general-purpose filtering applications

Applications

• Electromagnetic interference (EMI) filtering in electronic circuits
• Power supply input/output noise suppression
• Signal line protection in sensitive digital systems

Procurement Notes

Verify the specific manufacturing date code and lot traceability upon order confirmation. Ensure that the procurement channel provides authentic components from Knowles Syfer or authorized distributors. Confirm RoHS compliance status and packaging specifications match project requirements before finalizing purchase agreements.

Selection Notes

Select this component when high capacitance density is required within a standard 1206 footprint for EMI suppression. The three-terminal design offers superior high-frequency performance compared to standard two-terminal capacitors. Consider the X7R temperature characteristics and voltage derating curves for stable operation under varying environmental conditions.

Part Context

This part belongs to the Knowles Syfer MLCC series, specifically engineered for surface-mount technology. It integrates capacitor functionality with filtering properties, distinguishing it from standard passive components. The 1206 form factor allows for compact PCB layouts while maintaining robust electrical performance for industrial and commercial electronics.

Replacement Considerations

Direct substitutes must match the 1206 package, 50V rating, 120nF capacitance, X7R dielectric, and three-terminal EMI filter configuration. Verify terminal material compatibility and mounting orientation constraints when evaluating alternative manufacturers' offerings.
