Overview
The Knowles Syfer 1806Y1000563MXTE01 is a surface-mount feed-through capacitor designed for high-frequency noise suppression. It features a 56 nF capacitance with X7R dielectric and a 100 VDC rating. The component operates within a temperature range of -55°C to +125°C and includes an integrated 300 mA fuse element. Packaged in the 1806 (4516 metric) footprint, it utilizes flexible terminals to enhance board reliability.
Feature Summary
- Integrates a built-in fuse element for circuit protection against overcurrent conditions.
- Utilizes flexible terminal construction to reduce mechanical stress on the substrate.
- Provides efficient electromagnetic interference filtering through its feed-through architecture.
Applications
- High-frequency noise suppression in sensitive electronic circuits
- Power line filtering where overcurrent protection is required
- Applications requiring compact EMI mitigation solutions
Procurement Notes
Verify that the specific MXTE01 suffix aligns with the required fuse current rating and packaging configuration. Confirm compatibility with the target PCB footprint dimensions and thermal management requirements. Ensure the voltage derating meets the operational DC bias conditions to maintain capacitance stability and prevent premature failure during assembly or operation.
Selection Notes
Select this component when both EMI filtering and overcurrent protection are necessary within a single surface-mount package. The X7R dielectric offers stable performance across the specified industrial temperature range. Consider the 1806 footprint constraints and the need for flexible termination to accommodate mechanical strain in the final assembly design.
Part Context
This part belongs to the Knowles Syfer FlexiCap series, which emphasizes reliability through soft-termination technology. As a feed-through capacitor, it differs from standard MLCCs by incorporating a conductive path that allows signal transmission while shunting noise to ground. This integration simplifies layout by combining filtering and protection functions.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Verify pinout compatibility and electrical ratings before considering alternative manufacturers.
FAQ
What is the function of the MXTE01 designation?
The designation indicates a feed-through capacitor with an integrated fuse element rated at 300 mA, packaged in a reel format.
How does the flexible terminal benefit the application?
The flexible terminals absorb mechanical stress, reducing the risk of solder joint cracking and improving reliability in vibration-prone environments.
