1806J0500680MCTE01

Overview

The Knowles Syfer 1806J0500680MCTE01 is a three-terminal feed-through capacitor designed for surface mount technology. It features a capacitance of 68 pF with a C0G (NP0) dielectric, ensuring stable performance across varying conditions. The component has a DC voltage rating of 50 VDC and operates within a temperature range of -55°C to +125°C. Housed in an 1806 (4516 metric) package measuring 4.5 mm in length, 1.6 mm in width, and 1.1 mm in height, it provides effective electromagnetic interference filtering.

Feature Summary

• Three-terminal feed-through architecture for enhanced high-frequency noise suppression
• C0G (NP0) dielectric material providing minimal capacitance variation over temperature and voltage
• Surface mount design compatible with automated assembly processes

Applications

• High-frequency signal line filtering in communication equipment
• Power supply input/output decoupling in sensitive analog circuits
• Electromagnetic interference suppression in automotive electronics

Procurement Notes

Verify the specific suffix codes against official manufacturer documentation to confirm termination materials and tolerance specifications. Ensure compatibility with PCB footprint dimensions and reflow soldering profiles defined in the datasheet. Cross-reference part numbers with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when low parasitic inductance is critical for high-speed signal integrity. The C0G dielectric ensures predictable behavior in precision timing or RF applications. Consider the three-terminal configuration for superior grounding compared to standard two-terminal capacitors in dense layouts.

Part Context

This component belongs to the Knowles Syfer E01 series of ceramic capacitors. The series is engineered for general-purpose and high-reliability applications requiring stable capacitance values. The 1806 package size offers a balance between capacitance density and thermal management capabilities.

Replacement Considerations

Direct substitutes must match the 68 pF capacitance, 50 VDC rating, C0G dielectric, and 1806 three-terminal form factor. Verify that alternative parts maintain identical terminal configurations and electrical characteristics for seamless integration.
