1806J0500680MATE01

Overview

The Knowles Syfer 1806J0500680MATE01 is a Class 1 multilayer ceramic capacitor (MLCC) designed for surface-mount technology. It features a C0G (NP0) dielectric material, ensuring stable capacitance characteristics across varying temperatures and voltages. The component has a nominal capacitance of 68 pF with a tolerance of ±20%. It is rated for a maximum DC voltage of 50 VDC and operates within a temperature range of -55°C to +125°C. The physical dimensions conform to the EIA 1806 package size, measuring 4.5 mm in length, 1.6 mm in width, and 1.3 mm in height.

Feature Summary

• Utilizes C0G (NP0) dielectric for high stability and low loss in precision circuits
• Constructed as a high-reliability MLCC suitable for demanding environments
• Features standard SMD/SMT termination for automated assembly compatibility

Applications

• High-frequency RF signal coupling and filtering
• Precision timing and oscillator circuits requiring stable capacitance
• General-purpose decoupling in sensitive analog applications

Procurement Notes

Verify the specific suffix 'MAT' against official Knowles Syfer documentation to confirm termination plating and packaging details, as these variations can impact solderability and handling. Ensure the selected variant matches the required moisture sensitivity level and reel specifications for your manufacturing process. Cross-reference the full part number with the manufacturer's current datasheet to confirm availability and any recent design changes.

Selection Notes

Select this component when a small capacitance value with tight thermal stability is required in a compact 1806 footprint. The C0G dielectric makes it ideal for applications where capacitance drift must be minimized. Consider the 50V rating relative to peak circuit voltages to ensure adequate margin. Evaluate the 20% tolerance against circuit sensitivity requirements before finalizing the design.

Part Context

This part belongs to the Knowles Syfer high-reliability MLCC family, which emphasizes robust construction for industrial and commercial electronics. The 1806J series indicates a 50V rated device in the 1806 metric case size. These capacitors are engineered to meet stringent quality standards for long-term performance in critical electronic systems.

Replacement Considerations

Direct substitutes must match the 1806 package, 68 pF capacitance, 50V rating, and C0G dielectric. Verify that alternative manufacturers offer compatible termination materials and equivalent reliability ratings. Check for pin-out and dimensional tolerances to ensure mechanical fit in existing footprints.
