Overview
The Knowles Syfer 1812Y2000272MJTE03 is a multilayer ceramic capacitor (MLCC) in an 1812 (4532 metric) surface-mount package. It features X7R dielectric with a capacitance of 2.70 nF and a tolerance of ±20%. The component has a DC voltage rating of 200 VDC and operates within a temperature range of -55°C to +125°C. It utilizes FlexiCap technology with a nickel barrier and tin termination, ensuring high reliability under mechanical stress.
Feature Summary
- X2Y architecture providing integrated decoupling and filtering capabilities
- FlexiCap construction for enhanced resistance to mechanical stress and cracking
- Nickel barrier electrode structure for improved solderability and reliability
Applications
- High-reliability automotive electronics
- Industrial control systems requiring robust EMI suppression
- Space-constrained circuit boards needing combined decoupling and filtering
Procurement Notes
Verify the complete part number including the suffix to ensure correct termination and packaging specifications. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Cross-reference datasheet revisions to validate electrical parameters against current production batches.
Selection Notes
Select this component when space constraints require combining decoupling and filtering functions into a single device. The X2Y design reduces board area compared to discrete components. Ensure the 200V rating and X7R characteristics align with the specific circuit requirements and operating environment.
Part Context
This component belongs to the Knowles Syfer Y-series, which specializes in X2Y capacitors. These devices integrate three terminals to provide superior electromagnetic interference suppression. The series is designed for applications demanding high reliability and compact form factors in complex electronic systems.
Replacement Considerations
Direct substitutes must match the 1812 footprint, 200V rating, and X2Y topology. Verify terminal configuration and FlexiCap compatibility to maintain mechanical integrity.
