Overview
The Knowles Syfer 1206J2000123MXTE07 is a multilayer ceramic capacitor (MLCC) designed as a three-terminal EMI filter. It features a capacitance of 12 nF with a tolerance of ±20% and utilizes X7R dielectric material. The component is rated for a DC voltage of 200 V and operates within a temperature range of -55°C to +125°C. It employs a nickel barrier with 100% tin termination system and is housed in a standard 1206 (3216 metric) surface-mount package.
Feature Summary
- Three-terminal architecture providing enhanced electromagnetic interference suppression capabilities
- X7R dielectric composition ensuring stable electrical performance across specified operating temperatures
- Nickel barrier and 100% tin termination system for reliable solderability and corrosion resistance
Applications
- High-frequency noise filtering in electronic circuits
- Power supply line conditioning
- Signal integrity protection in sensitive digital systems
Procurement Notes
Verify the specific ordering suffix against official manufacturer documentation to confirm exact termination and packaging specifications. Ensure compatibility with existing PCB footprint designs before integration. Confirm RoHS compliance status through current datasheets. Check availability constraints as distribution may vary by region.
Selection Notes
Select this component when high-density EMI filtering is required in a compact 1206 footprint. The X7R dielectric offers a balance of capacitance density and stability suitable for general-purpose applications. Consider the three-terminal design for superior high-frequency attenuation compared to standard two-terminal capacitors.
Part Context
This part belongs to the Knowles Syfer SyferTech series of feedthrough capacitors. These components are engineered specifically for electromagnetic interference suppression in space-constrained environments. The product line emphasizes reliability and consistent performance in demanding electronic applications.
Replacement Considerations
Consult official substitution guides for compatible alternatives. Verify that any replacement maintains identical terminal configuration, voltage rating, and capacitance value to ensure circuit functionality.
