0805Y0250332MJTE07

Overview

The Knowles Syfer 0805Y0250332MJTE07 is a 3-terminal EMI filter multilayer ceramic capacitor in an 0805 (2012 metric) surface-mount package. It features a capacitance of 3300 pF with a ±20% tolerance and a DC voltage rating of 25V. The component utilizes X7R dielectric material and incorporates FlexiCap technology with a nickel barrier for enhanced mechanical reliability. Rated for operation between -55°C and +125°C, it provides effective electromagnetic interference suppression in compact designs.

Feature Summary

• Three-terminal architecture designed for superior high-frequency EMI filtering performance
• FlexiCap construction with nickel barrier to mitigate stress-induced cracking on flexible substrates
• X7R ceramic dielectric providing stable capacitance characteristics across the specified temperature range

Applications

• High-reliability electronic assemblies requiring robust EMI suppression
• Printed circuit boards susceptible to mechanical flexing or warping
• Compact signal conditioning circuits demanding efficient noise reduction

Procurement Notes

Verify the complete part number including the suffix to confirm the specific termination style and barrier composition. Ensure the selected variant matches the required capacitance tolerance and voltage rating for the target application. Cross-reference official datasheets to validate RoHS compliance status and environmental certifications prior to integration into production workflows.

Selection Notes

Select this component when board flexibility poses a risk to standard MLCC integrity. The three-terminal design offers lower impedance paths for high-frequency noise compared to two-terminal alternatives. Confirm that the 25V DC rating exceeds the maximum operating voltage in the circuit to ensure long-term reliability under thermal cycling conditions.

Part Context

This component belongs to the Knowles Syfer FlexiCap series, engineered specifically for applications involving substrate movement. The 0805 form factor allows for dense mounting patterns while maintaining the electrical performance necessary for sensitive signal lines. It represents a specialized solution within the broader category of high-reliability ceramic capacitors.

Replacement Considerations

Direct substitutes must match the 3-terminal EMI filter topology and 0805 footprint. Verify equivalent capacitance, voltage rating, and dielectric type. Standard 2-terminal capacitors lack the shielding benefits and may not provide identical high-frequency attenuation characteristics.
