Overview
The Knowles Syfer 1806J0500274MJTE07 is a surface-mount multilayer ceramic capacitor (MLCC) designed for EMI filtering applications. It features a 1806 (4516 metric) case size with a capacitance of 270 nF and a voltage rating of 50 VDC. The component utilizes X7R dielectric material, providing a tolerance of ±20%. It employs a three-terminal architecture with nickel barrier terminations and 100% tin plating to enhance solderability and reliability in high-frequency circuits.
Feature Summary
- Three-terminal EMI filter structure for effective noise suppression
- Nickel barrier termination technology for improved solder joint integrity
- X7R dielectric composition ensuring stable performance across temperature variations
Applications
- High-frequency signal line filtering
- Power supply input/output decoupling
- EMI suppression in sensitive electronic circuits
Procurement Notes
Verify the specific ordering suffix against official manufacturer documentation to ensure correct termination and packaging specifications. Confirm RoHS compliance status through current datasheets. Cross-reference Mouser part numbers and manufacturer codes to validate authenticity before procurement.
Selection Notes
Select this component when a 1806 footprint is required for EMI filtering at 50V. Ensure the circuit design accommodates the three-terminal configuration for proper ground connection. Verify that the X7R temperature characteristics meet the operational environment requirements.
Part Context
This component belongs to the Knowles Syfer MLCC series, specifically engineered for surface-mount applications. It falls under the category of ceramic capacitors with specialized EMI filtering capabilities, distinct from standard general-purpose capacitors due to its internal terminal arrangement.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source data. Consult official manufacturer cross-reference lists or authorized distributor databases for verified alternatives.
