1206J0500122MCTE01

Overview

The Knowles Syfer 1206J0500122MCTE01 is a three-terminal multilayer ceramic feed-through capacitor designed for surface-mount technology. It features a C0G (NP0) dielectric with a capacitance of 1200 pF and a tolerance of ±20%. The component has a DC voltage rating of 50 VDC and operates within a temperature range of -55°C to +125°C. Housed in a 1206 (3216 metric) package, it utilizes nickel barrier end terminations with 100% tin plating. This configuration provides effective electromagnetic interference filtering capabilities.

Feature Summary

• Three-terminal EMI filter architecture for enhanced noise suppression
• C0G (NP0) dielectric ensures stable capacitance across temperature variations
• Nickel barrier termination structure improves solderability and reliability

Applications

• High-frequency signal line filtering
• Power supply input/output decoupling
• EMI suppression in sensitive electronic circuits

Procurement Notes

Verify the specific suffix 'E01' against official datasheets to confirm terminal configuration and packaging details. Ensure compatibility with automated pick-and-place equipment regarding the 1206 footprint dimensions. Confirm RoHS compliance status through manufacturer documentation prior to integration into regulated assemblies.

Selection Notes

Select this component when high-frequency noise attenuation is required in space-constrained designs. The three-terminal design offers superior performance compared to standard two-terminal capacitors in grounding applications. Consider the 50V rating and 1200pF value for matching circuit impedance requirements without introducing significant phase shift due to the C0G material stability.

Part Context

This part belongs to the Knowles Syfer Syfer® family of high-reliability ceramic components. The '1206J' prefix indicates the 1206 case size and general product line. As a feed-through capacitor, it integrates shielding properties directly into the component body, distinguishing it from conventional MLCCs by providing a low-inductance path to ground for high-frequency interference.
