1812Y2000683MJTE03

Overview

The Knowles Syfer 1812Y2000683MJTE03 is a feed-through multilayer ceramic capacitor (MLCC) designed for surface mount applications. It features a capacitance of 0.068 µF and a DC voltage rating of 200 VDC. The component utilizes X7R dielectric material, providing stable performance across an operating temperature range of -55°C to +125°C. Housed in a compact 1812 (4532 Metric) package with a three-pad configuration, it integrates a central conductor for low-inductance signal routing. This design supports high-frequency filtering while maintaining structural integrity in demanding electronic environments.

Feature Summary

• Integrates a central conductor structure to minimize parasitic inductance for effective high-frequency noise suppression.
• Utilizes X7R dielectric characteristics to maintain capacitance stability over a wide industrial temperature range.
• Features a three-pad surface mount footprint that facilitates direct board integration and secure mechanical anchoring.

Applications

• High-speed digital signal line filtering
• Power supply decoupling in sensitive circuits
• EMI suppression in communication modules

Procurement Notes

Verify the specific suffix codes against official manufacturer documentation to confirm exact electrical tolerances and termination specifications. Ensure compatibility with automated pick-and-place equipment regarding the three-pad footprint dimensions. Cross-reference the latest datasheet revisions to confirm RoHS compliance status and recommended soldering profiles for reliable joint formation during assembly processes.

Selection Notes

Select this component when low-inductance filtering is critical for signal integrity in high-speed designs. The 1812 form factor offers a balance between current handling capability and board space efficiency compared to smaller packages. Consider the X7R temperature coefficient for applications where moderate capacitance variation within the operating range is acceptable. Evaluate the three-pad mounting requirement against available PCB real estate and thermal management constraints.

Part Context

This part belongs to the Knowles Syfer feed-through capacitor series, which specializes in integrated filtering solutions. Unlike standard MLCCs, these components combine capacitive filtering with conductive pathways. The 1812Y series designation indicates the case size and general product family, targeting applications requiring robust EMI/RFI mitigation without sacrificing trace continuity on the printed circuit board.
