1206J2000182MJTE03

Overview

The Knowles Syfer 1206J2000182MJTE03 is a surface-mount multilayer ceramic capacitor (MLCC) designed for high-frequency noise suppression. It features a 1206 (3216 metric) package size with a capacitance of 1800 pF and a voltage rating of 200 VDC. The component utilizes X7R dielectric material, offering a tolerance of ±20%. It is constructed as a three-terminal feed-through capacitor, providing enhanced electromagnetic interference (EMI) filtering capabilities compared to standard two-terminal devices.

Feature Summary

• Three-terminal feed-through architecture for superior EMI/RFI suppression
• X7R dielectric stability across operating temperature ranges
• High-voltage handling capability within compact SMD footprint

Applications

• High-speed digital signal line filtering
• Power supply input/output decoupling in noisy environments
• Automotive electronics requiring robust EMI protection

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure compatibility with required termination materials and barrier layers. Confirm that the three-terminal pin configuration matches the PCB layout design, as this differs from standard MLCC footprints. Check for any recent revisions to the RoHS compliance status or packaging specifications before finalizing procurement orders.

Selection Notes

Select this component when standard two-terminal capacitors fail to meet EMI attenuation requirements due to parasitic inductance. The three-terminal design offers lower effective series inductance (ESL). Ensure the circuit operates within the 200V DC rating and consider the thermal management implications of the X7R dielectric at maximum operating temperatures.

Part Context

This part belongs to the Knowles Syfer J-series of high-performance MLCCs. The 'J' designation typically indicates specific voltage and dielectric characteristics within the product line. It is engineered for applications demanding reliable noise suppression in space-constrained designs, leveraging advanced ceramic processing techniques to maintain performance under electrical stress.

Replacement Considerations

Direct substitutes must match the 1206 package, 1800pF capacitance, 200V rating, and critically, the three-terminal feed-through structure. Standard two-terminal replacements will not provide equivalent EMI filtering performance. Verify pinout compatibility and mounting orientation differences.
