1806J1000183MJTE07

Overview

The Knowles Syfer 1806J1000183MJTE07 is a surface-mount multilayer ceramic capacitor (MLCC) designed for high-reliability applications. It features an EIA 1806 package size with X7R dielectric characteristics, providing stable capacitance across a wide temperature range. The component offers a nominal capacitance of 18 nF with a tolerance of ±20% and a DC voltage rating of 100 VDC. It utilizes nickel barrier terminations with 100% tin plating to ensure robust solderability and mechanical integrity in automated assembly processes.

Feature Summary

• Utilizes X7R dielectric material for consistent performance under varying thermal conditions
• Features nickel barrier termination technology combined with 100% tin plating for enhanced reliability
• Designed as a high-reliability MLCC suitable for demanding electronic environments

Applications

• High-reliability industrial electronics
• Automotive circuitry requiring robust passive components
• General-purpose filtering and decoupling in SMD/SMT assemblies

Procurement Notes

Verify the specific ordering suffix against official Knowles Syfer documentation to confirm termination type and packaging configuration. Ensure compatibility with standard reflow soldering profiles. Confirm RoHS compliance status through current manufacturer declarations before integration into regulated supply chains.

Selection Notes

Select this component when a 1806 footprint is required with 100V capability and moderate capacitance stability. The X7R dielectric balances cost and performance for general applications. Verify that the ±20% tolerance meets circuit requirements compared to tighter tolerance alternatives like J or K grades.

Part Context

This part belongs to the Knowles Syfer high-reliability MLCC family, which emphasizes durability and consistency for critical systems. The 1806J series specifically targets applications needing reliable surface-mount capacitors with standardized dimensions. It complements other variants in the lineup offering different voltage ratings and capacitance values within the same physical envelope.

Replacement Considerations

Direct substitutes include other 1806 package MLCCs with identical 100V DC rating, 18nF capacitance, and X7R dielectric. Ensure replacement parts maintain compatible termination metallurgy and operate within the same -55°C to +125°C temperature range.
