Overview
The Knowles Syfer 0805Y1000223MXTE07 is a three-terminal EMI feedthrough capacitor housed in an 0805 (2012 metric) surface-mount package. It features a 22 nF capacitance with ±20% tolerance and utilizes X7R dielectric material. The component is rated for a DC voltage of 100 V and operates within a temperature range of -55°C to +125°C. It incorporates FlexiCap technology with nickel barrier and tin terminations to enhance mechanical reliability.
Feature Summary
- Three-terminal EMI filter architecture for effective noise suppression
- FlexiCap soft termination design to reduce board stress
- Nickel barrier and tin plating for reliable soldering
Applications
- EMI filtering in high-density electronic circuits
- Signal integrity protection in sensitive communication modules
- Power supply decoupling in automotive electronics
Procurement Notes
Verify the complete part number including suffixes against official manufacturer documentation to ensure correct termination and dielectric specifications. Confirm RoHS compliance status and moisture sensitivity level requirements prior to procurement. Ensure storage conditions align with manufacturer guidelines to maintain component integrity before assembly.
Selection Notes
Select this component when board flexure resistance is critical due to its soft termination structure. The three-terminal configuration provides superior high-frequency attenuation compared to standard two-terminal capacitors. Verify that the 100V rating and 22nF value meet the specific circuit requirements for EMI suppression applications.
Part Context
This component belongs to the Knowles Syfer XT series of multi-layer ceramic capacitors. It is specifically engineered as an EMI feedthrough filter, combining standard MLCC electrical performance with enhanced mechanical durability. The 0805 footprint allows for compact PCB layouts while maintaining robust filtering capabilities.
Replacement Considerations
Direct substitutes must match the 0805 footprint, 100V rating, 22nF capacitance, and three-terminal EMI filter topology. Verify compatibility of FlexiCap or equivalent soft-termination features if board stress is a concern. Cross-reference datasheets for identical temperature coefficients and termination materials.
