Overview
The Knowles Syfer 0805Y1000821MXTE01 is a three-terminal EMI filter capacitor in an 0805 (2012 metric) surface-mount package. It features an X7R dielectric with a capacitance of 820 pF and a DC voltage rating of 100 V. The component utilizes FlexiCap technology with flexible terminals to enhance board flex sensitivity. It operates within a temperature range of -55°C to +125°C and has a maximum height of 1.15 mm.
Feature Summary
- Three-terminal EMI filter design for enhanced noise suppression
- FlexiCap flexible terminal construction for board flex sensitivity
- X7R dielectric material for stable performance across temperature ranges
Applications
- Boardflex sensitive electronic assemblies
- EMI filtering in high-density surface mount circuits
- Automotive grade applications requiring AEC-Q200 compliance
Procurement Notes
Verify the specific suffix MXTE01 against official datasheets to confirm the three-terminal configuration and nickel barrier plating. Ensure compatibility with automated pick-and-place equipment due to the specific package dimensions. Confirm RoHS3 compliance status prior to final procurement integration.
Selection Notes
Select this component when EMI filtering is required in space-constrained designs. The three-terminal structure offers superior high-frequency attenuation compared to standard two-terminal capacitors. Verify that the 100V rating meets circuit requirements and that the 0805 footprint aligns with the PCB layout constraints.
Part Context
This part belongs to the Knowles Syfer FlexiCap series, which specializes in multilayer ceramic capacitors designed for reliability in mechanically stressed environments. The 0805Y series provides various capacitance values and voltage ratings within the standard 0805 footprint, balancing performance with compact size.
Replacement Considerations
Direct substitutes must match the three-terminal EMI filter topology and 0805 footprint. Standard two-terminal capacitors are not equivalent replacements as they lack the specific filtering characteristics. Verify terminal flexibility and voltage ratings before considering alternative manufacturers.
