Overview
The Knowles Syfer 1206J0500563MJTE03 is an X2Y integrated surface mount EMI filter capacitor. It features a capacitance of 56 nF with a ±20% tolerance and a DC voltage rating of 50 VDC. The component utilizes X7R dielectric material and operates within a temperature range of -55°C to +125°C. Housed in a 1206 (3216 metric) package, it provides three terminals for effective noise suppression.
Feature Summary
- Integrates three-terminal X2Y architecture for enhanced electromagnetic interference filtering
- Provides high capacitance density within a compact surface-mount footprint
- Utilizes stable X7R ceramic dielectric for consistent performance across operating temperatures
Applications
- High-speed digital signal line protection
- Power supply input/output filtering
- EMI suppression in automotive electronics
- Noise reduction in communication interfaces
Procurement Notes
Verify the exact part number against official Knowles Syfer documentation to confirm availability and specifications. Ensure compatibility with existing PCB footprints and thermal requirements. Cross-reference datasheets for any recent manufacturing updates or compliance changes before finalizing procurement decisions.
Selection Notes
Select this component when space-constrained designs require superior common-mode noise rejection compared to standard two-terminal capacitors. The three-terminal configuration allows for shorter ground paths, reducing parasitic inductance. Consider the X7R characteristics for applications requiring moderate stability over varying temperature conditions.
Part Context
This component belongs to the Knowles Syfer X2Y series, which combines capacitor and inductor functions into a single monolithic structure. The series is designed for efficient EMI filtering in dense electronic assemblies. The 1206J prefix indicates the specific case size and voltage class within the broader product portfolio.
