Overview
The Knowles Syfer 1206J2000392MJTE03 is a surface-mount multilayer ceramic capacitor (MLCC) in the 1206 (3216 metric) package. It features a C0G (NP0) dielectric with a capacitance of 3900 pF and a tolerance of ±2%. The component has a rated DC voltage of 200 VDC and operates within a temperature range of -55°C to +125°C. It utilizes standard SMD/SMT terminations.
Feature Summary
- Utilizes C0G (NP0) dielectric for stable capacitance characteristics across varying temperatures and voltages.
- Designed as a high-reliability MLCC suitable for demanding electronic environments.
- Features standard surface-mount terminations for automated assembly integration.
Applications
- High-reliability general-purpose circuits
- Precision timing and filtering applications
- Industrial control systems
Procurement Notes
Verify the complete part number including the suffix '03' against official manufacturer documentation to ensure correct termination and packaging specifications. Confirm RoHS compliance status through current datasheets, as environmental declarations may be updated. Cross-reference the Mouser part number 843-1206J2000392MJTE03 for accurate distributor identification and availability status.
Selection Notes
Select this component when a stable Class 1 capacitor is required in a 1206 footprint with a 200V rating. The C0G dielectric ensures minimal capacitance change over temperature and bias. Ensure the application does not require the enhanced mechanical flexibility or specific barrier plating found in other Knowles Syfer series such as FlexiCap or high-voltage nickel barrier variants.
Part Context
This component belongs to the Knowles Syfer General Type MLCC line, distinct from their specialized FlexiCap or high-voltage product families. It represents a standard high-reliability ceramic capacitor solution designed for broad industrial and commercial applications where stability and size are prioritized.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Verify compatibility with alternative manufacturers by matching capacitance, voltage rating, tolerance, dielectric type, and physical dimensions.
