Overview
The Knowles Syfer 1206J0500222MJTE03 is an X2Y integrated surface mount EMI filter feedthrough capacitor. It features a capacitance of 2200 pF with a tolerance of ±20%. The device has a DC voltage rating of 50 VDC and utilizes an X7R dielectric material. It is housed in a 1206 (3216 metric) package with SMD/SMT termination. The component operates within a temperature range of -55°C to +125°C.
Feature Summary
- Integrates three-terminal X2Y architecture for simultaneous common-mode and differential-mode noise suppression
- Utilizes nickel barrier and 100% tin termination structure for enhanced solderability and reliability
- Provides high capacitance density within a compact 1206 surface-mount footprint
Applications
- High-speed data line filtering in portable electronic devices
- EMI suppression on power distribution networks in automotive electronics
- Signal integrity protection in industrial control systems
Procurement Notes
Verify the specific ordering suffix against the manufacturer's current datasheet to confirm termination plating and packaging details. Ensure compatibility with standard reflow soldering profiles for 1206 packages. Confirm RoHS compliance status through official documentation prior to integration into regulated assemblies.
Selection Notes
Select this component when space-constrained designs require combined common-mode and differential-mode filtering capabilities. The X7R dielectric offers stable performance across the specified operating temperature range. Evaluate the 50V DC rating against peak circuit voltages to ensure adequate margin for long-term reliability.
Part Context
This part belongs to the Knowles Syfer X2Y IPC-E03 series of feedthrough capacitors. These components are designed to replace multiple discrete capacitors, reducing board space and improving high-frequency performance by minimizing parasitic inductance associated with traditional two-terminal configurations.
Replacement Considerations
Direct substitutes include other X2Y feedthrough capacitors from Knowles Syfer with identical 1206 dimensions and similar electrical ratings. Verify pinout compatibility and thermal characteristics before substituting with generic three-terminal capacitors.
