Overview
The Knowles Syfer 1806Y0250123MJTE07 is a three-terminal EMI filter capacitor in an 1806 (4516 metric) surface-mount package. It features a 12 nF capacitance with ±20% tolerance and X7R dielectric, rated for 25 VDC. The component utilizes FlexiCap technology with nickel barrier terminations to enhance mechanical reliability. Designed for high-frequency noise suppression, it supports operating temperatures from -55°C to +125°C.
Feature Summary
- Three-terminal architecture provides effective electromagnetic interference filtering through integrated ground connection.
Applications
- High-frequency noise suppression in sensitive electronic circuits
- Power supply input/output filtering applications
- Signal line protection against electromagnetic interference
Procurement Notes
Verify the complete part number including suffixes to ensure correct termination and dielectric specifications. Confirm RoHS compliance status and manufacturing origin during sourcing. Check datasheet for specific handling requirements related to the nickel barrier and FlexiCap structure to prevent damage during assembly.
Selection Notes
Select this component when board space constraints require a compact 1806 footprint with integrated filtering capabilities. The X7R dielectric offers stable performance across a wide temperature range suitable for general industrial environments. Ensure the 25V rating exceeds the maximum circuit voltage to maintain reliability under operational stress.
Part Context
This component belongs to the Knowles Syfer FlexiCap series, which specializes in multilayer ceramic capacitors with flexible terminations. The series is engineered to withstand mechanical stress and thermal cycling better than standard rigid-termination MLCCs, making it suitable for high-reliability applications where board flexing may occur.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing designs by matching capacitance, voltage rating, package dimensions, and terminal configuration before substitution.
