Overview
The Knowles Syfer 1806J0500392MJTE07 is a surface-mount multilayer ceramic capacitor (MLCC) designed for high-reliability applications. It features a 1806 (4516 metric) case size with a capacitance of 3900 pF and a DC voltage rating of 50 VDC. The component utilizes X7R dielectric material, providing a tolerance of ±20%. It operates within a temperature range of -55°C to +125°C and employs standard SMD/SMT terminations.
Feature Summary
- Utilizes X7R dielectric material for stable capacitance characteristics across the operating temperature range.
- Designed as a high-reliability MLCC suitable for demanding electronic environments.
- Features a compact 1806 surface-mount package for efficient PCB integration.
Applications
- High-reliability general-purpose electronics
- Industrial control systems requiring stable filtering
- Automotive electronics components
Procurement Notes
Verify the specific suffix 'MJTE07' against official Knowles Syfer documentation to confirm terminal plating and packaging details. Ensure the X7R dielectric and 50V rating align with circuit requirements. Cross-reference the Mouser number 843-06j0500204mjte07 if available in catalogs, but prioritize the manufacturer's part number for accuracy during sourcing.
Selection Notes
Select this component when a 3900 pF capacitance at 50 VDC is required in an 1806 footprint. The X7R dielectric offers higher volumetric efficiency than Class 1 alternatives. Confirm that the ±20% tolerance meets the circuit's precision needs. Ensure the operating environment stays within the specified -55°C to +125°C range for optimal performance.
Part Context
This part belongs to the Knowles Syfer 1806J series of high-reliability multilayer ceramic capacitors. The series is characterized by robust construction and consistent electrical performance. It serves as a passive component for decoupling, filtering, and timing applications in modern electronic assemblies.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source data. Verify compatibility with any alternative MLCCs based on identical capacitance, voltage rating, dielectric type, and physical dimensions before implementation.
