Overview
The Knowles Syfer 1812J2000272MXTE03 is a multilayer ceramic capacitor (MLCC) in an 1812 surface-mount package. It features X7R dielectric with a capacitance of 2700 pF and a DC voltage rating of 200 VDC. The component offers a tolerance of ±20% and operates within a temperature range of -55°C to +125°C. It utilizes a nickel barrier termination with 100% tin plating and is classified as an X2Y device.
Feature Summary
- X2Y architecture providing integrated common-mode filtering capabilities
- Nickel barrier termination structure for enhanced reliability
- High-temperature stability utilizing X7R dielectric material
Applications
- Common-mode noise suppression in high-speed digital circuits
- Power supply line filtering for EMI reduction
- Signal integrity protection in sensitive electronic interfaces
Procurement Notes
Verify the specific suffix TE03 against official manufacturer documentation to confirm packaging configuration and termination specifications. Ensure compatibility with automated placement equipment regarding the 1812 footprint dimensions. Cross-reference RoHS compliance status directly with the current datasheet revision prior to procurement.
Selection Notes
Select this component when integrated common-mode filtering is required in a compact form factor. The X2Y design reduces board space compared to discrete solutions. Verify that the 200V rating and 2700pF value meet circuit requirements. Confirm thermal management needs align with the X7R characteristics and operating temperature limits.
Part Context
This part belongs to the Knowles Syfer X2Y family, which integrates three terminals into a single MLCC structure. The series is designed for applications requiring effective noise suppression without increasing component count. The 1812 case size balances performance with standard SMT manufacturing processes.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source data. Consult official manufacturer cross-reference tools for verified alternatives.
