0805Y0500272MXTE01

Overview

The Knowles Syfer 0805Y0500272MXTE01 is a three-terminal EMI filter capacitor in an 0805 (2012 metric) surface-mount package. It features a 2.7 nF capacitance with ±20% tolerance and a 50 VDC voltage rating. The component utilizes X7R dielectric material and incorporates FlexiCap™ technology with nickel barrier terminations for enhanced mechanical reliability. It operates within a temperature range of -55°C to +125°C and carries AEC-Q200 qualification.

Feature Summary

• Three-terminal architecture designed for effective electromagnetic interference filtering
• FlexiCap™ termination system provides superior resistance to board flexing and thermal cycling
• Nickel barrier plating ensures robust solderability and environmental protection

Applications

• Board-flex sensitive electronic assemblies
• Automotive electronics requiring AEC-Q200 compliance
• High-reliability space applications

Procurement Notes

Verify the specific suffix E01 confirms the three-terminal feedthrough configuration, as standard two-terminal variants exist within the same series. Confirm RoHS3 compliance status and REACH SVHC declarations prior to integration. Ensure the procurement documentation explicitly states the nickel barrier termination type to distinguish it from standard silver-palladium options.

Selection Notes

Select this component when high-frequency noise suppression is required alongside mechanical durability in flexible circuit environments. The three-terminal design offers superior grounding compared to standard two-terminal capacitors. Verify that the 0805 footprint accommodates the specific pad layout required for three-terminal devices to ensure proper thermal and electrical performance during assembly.

Part Context

This part belongs to the Knowles Syfer FlexiCap™ SMD MLCC family, which utilizes proprietary flexible termination materials to withstand board bending. The series has received the Queen’s Award for Innovation and is qualified for space applications. The 'Y' in the model number indicates the 0805 case size, while 'E01' denotes the specific three-terminal EMI filter variant.

Replacement Considerations

Direct substitutes include other 0805 three-terminal EMI filters with matching 2.7 nF capacitance and 50V ratings. Verify that replacement parts also feature flexible terminations if board flex resistance is critical. Cross-reference pinout configurations to ensure the ground terminal placement matches the existing PCB layout.
