Overview
The Knowles Syfer 1812J1000684MXTE07 is a surface-mount multilayer ceramic capacitor (MLCC) designed for EMI filtering applications. It features a capacitance of 680 nF with a ±20% tolerance, rated for a DC voltage of 100V. The component utilizes X7R dielectric material and operates within a temperature range of -55°C to +125°C. Housed in an 1812 (4532 metric) package, it employs a three-terminal structure with nickel barrier and 100% tin terminations.
Feature Summary
- Three-terminal EMI filter architecture for enhanced noise suppression
- X7R dielectric material providing stable performance across operating temperatures
- Nickel barrier and 100% tin termination system for reliable soldering
Applications
- General purpose MLCC EMI filtering
- Power supply input/output decoupling
- Signal line noise suppression
Procurement Notes
Verify the specific suffix 'T07' against official manufacturer documentation to confirm packaging details such as reel size or tape specifications. Ensure compatibility with standard SMD reflow profiles. Confirm RoHS compliance status through the latest datasheet revision before final procurement decisions.
Selection Notes
Select this component when high capacitance density is required in a compact 1812 footprint for EMI mitigation. The X7R characteristic offers a balance between cost and stability. Verify that the 100V rating exceeds the peak circuit voltage and that the three-terminal design fits the available PCB real estate for ground plane integration.
Part Context
This part belongs to the Knowles Syfer 1812J series of ceramic capacitors. The series includes various capacitance values and voltage ratings tailored for general electronic applications. The 1812J designation indicates the case size family, while the internal coding specifies the electrical parameters and termination style unique to this specific unit.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source data. Cross-referencing requires matching the 680nF value, 100V rating, X7R dielectric, and three-terminal EMI filter form factor from other manufacturers.
