0805Y0250473MXTE01

Overview

The Knowles Syfer 0805Y0250473MXTE01 is a feed-through multilayer ceramic capacitor (MLCC) designed for high-frequency noise suppression. It features a capacitance of 0.047 µF with a voltage rating of 25V DC and a current rating of 300 mA. The component utilizes an X7R dielectric material, ensuring stable performance across a temperature range of -55°C to +125°C. Housed in a compact 0805 (2012 metric) surface-mount package, it integrates a central conductor for efficient grounding. This design provides effective electromagnetic interference (EMI) filtering while maintaining low parasitic inductance.

Feature Summary

• Integrated feed-through architecture enables direct connection to ground planes for superior EMI suppression.
• Flexible terminal construction accommodates board flexing, enhancing reliability in sensitive applications.
• X7R dielectric offers consistent capacitance stability over the specified operating temperature range.

Applications

• High-speed digital signal line filtering
• Power supply input/output decoupling
• RF circuit noise attenuation

Procurement Notes

Verify the specific suffix 'E01' against official manufacturer documentation to confirm terminal configuration and packaging details. Ensure compatibility with standard 0805 footprints during PCB layout. Confirm RoHS compliance status through the latest datasheet revision. Cross-reference part numbers with authorized distributors to avoid counterfeit components. Validate thermal and electrical ratings against final application requirements before procurement.

Selection Notes

Select this component when space-constrained EMI filtering is required on high-density boards. The feed-through design reduces loop inductance compared to standard MLCCs. Consider the 300 mA current rating for power integrity needs. Evaluate the X7R characteristics for temperature-dependent capacitance shifts. Compare against standard capacitors if higher current handling or different dielectric stability is necessary.
