1206J0250182MCTE01

Overview

The Knowles Syfer 1206J0250182MCTE01 is a surface-mount feedthrough capacitor designed for EMI suppression. It features a capacitance of 1800 pF with a tolerance of ±20% and a DC voltage rating of 25 VDC. 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 supports a maximum current of 300 mA and provides insertion loss of 27 dB at 100 MHz.

Feature Summary

• Integrated feedthrough architecture enables direct signal line integration for effective electromagnetic interference filtering
• C0G (NP0) dielectric construction maintains consistent electrical characteristics under varying thermal conditions
• High current handling capability allows operation within power distribution or high-speed data lines

Applications

• Electromagnetic interference suppression in high-speed digital circuits
• Signal integrity protection in communication interfaces
• Power line filtering in compact electronic modules

Procurement Notes

Verify the complete part number including suffixes against official manufacturer documentation to ensure correct dielectric type and termination specifications. Confirm RoHS compliance status and moisture sensitivity level requirements prior to procurement. Cross-reference datasheet revision dates to validate technical parameters. Ensure storage and handling procedures align with industry standards for ceramic components.

Selection Notes

Select this component when space-constrained designs require integrated EMI filtering without additional discrete inductors. The 1206 footprint offers a balance between current capacity and board area efficiency. Verify that the 25V rating exceeds peak circuit voltages and that the 300mA limit accommodates operational current demands. Consider the 27dB insertion loss specification relative to required attenuation levels at target frequencies.

Part Context

This component belongs to the Knowles Syfer 1206J series of surface-mount EMI filters. These devices are engineered for high-reliability applications requiring robust noise suppression in minimal footprints. The series integrates capacitor functionality directly into the package structure, distinguishing it from standard multilayer ceramic capacitors by providing inherent shielding and grounding paths through the central conductor.

Replacement Considerations

Direct substitutes must match the 1206 footprint, 1800pF capacitance, 25V rating, and feedthrough topology. Verify equivalent insertion loss characteristics and current ratings. Check for compatible termination materials and soldering profiles. Consult manufacturer cross-reference lists for validated alternatives.
