1806J0500820MATE01

Overview

The Knowles Syfer 1806J0500820MATE01 is a surface-mount multilayer ceramic capacitor (MLCC) designed for high-reliability applications. It features a C0G (NP0) dielectric material, ensuring stable capacitance characteristics over varying temperature and voltage conditions. The component has a nominal capacitance of 82 pF with a tolerance of ±20%. It is rated for a maximum DC working voltage of 50 VDC. The physical dimensions conform to the standard 1806 (4516 metric) case size, measuring 4.5 mm in length, 1.6 mm in width, and 1.3 mm in height. It operates within a temperature range of -55°C to +125°C.

Feature Summary

• Utilizes C0G (NP0) dielectric for minimal capacitance change with temperature and voltage variations.
• Constructed as a high-reliability MLCC suitable for demanding electronic environments.
• Features standard SMD/SMT termination type for automated surface-mount assembly processes.

Applications

• High-frequency signal coupling and decoupling circuits
• RF filter networks requiring stable capacitance
• Precision timing and oscillator circuits

Procurement Notes

Verify the specific suffix 'MA' against official Knowles Syfer documentation to confirm termination plating and packaging specifications. Ensure the selected variant matches the required moisture sensitivity level and reel quantity for your manufacturing process. Cross-reference the datasheet revision date to confirm compliance with current RoHS and REACH regulations before finalizing procurement orders.

Selection Notes

Select this component when a small form factor (1806) is required alongside high stability. The C0G dielectric is essential for applications where capacitance drift affects circuit performance. Consider the 50V rating relative to peak transient voltages in the target application. Evaluate thermal management needs given the operating range up to 125°C.

Part Context

This part belongs to the Knowles Syfer high-reliability MLCC family. These capacitors are engineered for aerospace, defense, and industrial sectors where long-term reliability and consistent electrical performance are critical. The 1806 case size offers a balance between capacitance value potential and board space efficiency compared to smaller packages like 0603 or 0402.

Replacement Considerations

Direct substitutes must match the 1806 footprint, 82 pF capacitance, 50V rating, and C0G dielectric. Verify that alternative manufacturers offer compatible termination materials and soldering profiles. Check if any pin-compatible alternatives provide improved moisture resistance or higher reliability ratings for harsh environments.
