1206J0250122MCTE01

Overview

The Knowles Syfer 1206J0250122MCTE01 is a surface-mount feed-through capacitor designed for high-frequency noise suppression. It features a capacitance of 1200 pF with a DC voltage rating of 25 VDC and a current rating of 300 mA. The component utilizes C0G/NP0 dielectric material, ensuring stable performance across an operating temperature range of -55°C to +125°C. Housed in a standard 1206 (3216 metric) package, it offers low impedance characteristics suitable for EMI filtering applications.

Feature Summary

• Integrates three-terminal feed-through architecture for enhanced electromagnetic interference suppression within compact surface-mount footprints.
• Utilizes C0G/NP0 ceramic dielectric to maintain consistent capacitance stability under varying thermal conditions and electrical loads.
• Engineered for high-current handling capabilities, supporting continuous operation at specified ratings without degradation.

Applications

• High-frequency noise filtering in sensitive electronic circuits
• Electromagnetic interference suppression in power distribution lines
• Signal integrity protection in communication equipment

Procurement Notes

Verify the specific suffix codes against official manufacturer documentation to confirm exact termination plating and packaging configurations. Ensure compatibility with automated pick-and-place processes by checking reel specifications. Confirm RoHS compliance status through the latest datasheet revision before integration into regulated assemblies.

Selection Notes

Select this component when space-constrained designs require effective common-mode noise reduction. The 1206 footprint balances board area efficiency with adequate current handling. Consider the C0G dielectric for applications demanding minimal capacitance drift over temperature variations compared to X7R alternatives.

Part Context

This part belongs to the Knowles Syfer EMI Filter series, specifically utilizing the E01 or similar SMT feed-through technology. It represents a specialized class of multilayer ceramic capacitors designed to replace traditional discrete filter components, offering superior performance in dense PCB layouts requiring robust signal conditioning.

Replacement Considerations

Direct substitutes must match the 1206 footprint, 1200 pF capacitance, and 25 VDC rating. Verify that alternative feed-through capacitors provide comparable insertion loss characteristics and current ratings to ensure circuit performance parity.
