Overview
The Knowles Syfer 1206J0500123MXTE07 is a surface-mount feed-through capacitor designed for EMI suppression. It features a capacitance of 0.012 µF with a ±20% tolerance and an X7R dielectric. The component operates at a rated DC voltage of 50V and supports a continuous current of 2A. Housed in a 1206 (3216 metric) package, it utilizes a three-terminal structure with nickel barrier and 100% tin terminations to ensure reliable soldering.
Feature Summary
- Three-terminal feed-through architecture provides effective electromagnetic interference filtering within a compact footprint.
- Nickel barrier and 100% tin termination system ensures robust solderability and connection integrity.
- X7R ceramic dielectric maintains stable electrical performance across the specified operating temperature range.
Applications
- High-frequency signal line filtering
- Power supply input/output noise suppression
- General-purpose EMI mitigation in compact electronics
Procurement Notes
Verify the complete part number including suffixes against official manufacturer documentation to confirm specific termination and packaging details. Ensure compatibility with existing PCB layout constraints regarding the three-terminal configuration. Confirm RoHS compliance status through the latest datasheet before integration into regulated products.
Selection Notes
Select this component when high current handling capability is required alongside EMI filtering in a standard 1206 footprint. The 50V rating suits low-voltage digital and analog circuits. Consider the three-terminal design implications on board routing compared to standard two-terminal capacitors.
Part Context
This component belongs to the Knowles Syfer SMT EMI Filter series, specifically the E07 type. These devices are engineered for applications demanding superior noise reduction in space-constrained environments. The series integrates capacitor functionality with shielding properties inherent to the feed-through design.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Verify pinout and electrical specifications carefully if considering alternative manufacturers' feed-through capacitors.
