Overview
The Knowles Syfer 1806Y0250333MXTE07 is a multilayer ceramic capacitor (MLCC) in an 1806 surface-mount package. It features a capacitance of 33 nF with a ±20% tolerance and a DC voltage rating of 25 VDC. The dielectric material is X7R, providing stable performance across a temperature range of -55°C to +125°C. This component utilizes the FlexiCap technology with a nickel barrier and soft terminations to enhance mechanical reliability.
Feature Summary
- FlexiCap technology with soft terminations for board-flex sensitivity
- Nickel barrier construction for enhanced durability
- Three-terminal design functioning as an EMI filter
Applications
- Board-flex sensitive circuit designs
- EMI filtering applications
- General purpose SMD/SMT mounting
Procurement Notes
Verify the specific ordering suffix against official manufacturer documentation to confirm terminal composition and barrier specifications. Ensure compatibility with PCB layout requirements for three-terminal EMI filter configurations. Cross-reference datasheet revision dates to validate current RoHS compliance status and environmental declarations prior to final procurement decisions.
Selection Notes
Select this component when board flex resistance is critical due to its soft termination structure. The three-terminal architecture provides inherent EMI suppression capabilities suitable for noise-sensitive environments. Confirm that the 1806 footprint aligns with existing PCB constraints and that the X7R dielectric characteristics meet the operational temperature requirements of the target application.
Part Context
This part belongs to the Knowles Syfer FlexiCap series, which specializes in capacitors designed to withstand mechanical stress during PCB bending or warping. The 1806Y prefix indicates the case size and voltage class within the broader MLCC portfolio. These components are engineered for high-reliability applications where standard rigid terminations might fail under thermal or mechanical strain.
Replacement Considerations
Direct substitutes include other 1806 Y-series parts from Knowles Syfer with matching capacitance and voltage ratings, such as 1806Y0250333KXT, provided the three-terminal EMI filter feature is not required.
