0805Y0250473MXTE07

Overview

The Knowles Syfer 0805Y0250473MXTE07 is a three-terminal EMI filter capacitor in an 0805 (2012 metric) surface-mount package. It features a 47 nF capacitance with ±20% tolerance and a 25 VDC voltage rating, utilizing X7R dielectric material. The component incorporates nickel barrier construction with 100% tin terminations for solderability. Designed for high-frequency noise suppression, it operates within a temperature range of -55°C to +125°C.

Feature Summary

• Three-terminal architecture providing enhanced electromagnetic interference filtering compared to standard two-terminal capacitors
• Nickel barrier termination system ensuring reliable soldering and mechanical stability on the printed circuit board
• X7R ceramic dielectric offering stable capacitance performance across the specified industrial operating temperature range

Applications

• High-speed digital signal line filtering in communication equipment
• Power supply input/output decoupling in compact electronic modules
• Noise suppression in sensitive analog circuits requiring low-profile components

Procurement Notes

Verify the specific suffix MXTE07 against the manufacturer's current datasheet to confirm terminal composition and packaging details. Ensure design compatibility with the 0805 footprint dimensions and thermal requirements during assembly processes.

Selection Notes

Select this component when board space is limited but superior high-frequency attenuation is required. The three-terminal design offers better parasitic inductance reduction than standard MLCCs. Confirm that the 25V rating meets the circuit's peak voltage demands under all operating conditions.

Part Context

This part belongs to the Knowles Syfer FlexiCap family of multi-layer ceramic capacitors. The series is characterized by flexible terminations designed to reduce stress on the ceramic body during board flexing. This specific model integrates EMI filtering capabilities within the standard SMD form factor.

Replacement Considerations

Direct substitutes must match the 0805 footprint, 47nF value, 25V rating, and three-terminal configuration. Verify that alternative parts maintain similar insertion loss characteristics and thermal stability profiles for equivalent circuit performance.
