Overview
The Knowles Syfer 0805Y0250222MXTE07 is a three-terminal EMI filter capacitor in an 0805 (2012 metric) surface-mount package. It features a 2.2 nF capacitance with ±20% tolerance and a 25 VDC voltage rating. The component utilizes X7R dielectric material and incorporates a nickel barrier structure with 100% tin terminations. 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 capabilities
- Nickel barrier construction with 100% tin terminations for reliable soldering
- X7R ceramic dielectric ensuring stable performance across the specified operating temperature range
Applications
- High-frequency noise suppression in sensitive electronic circuits
- Power line filtering in compact surface-mount designs
- EMI mitigation in telecommunications equipment
Procurement Notes
Verify the exact part number suffix against official manufacturer documentation to confirm terminal configuration and termination material specifications. Ensure compatibility with PCB pad layouts designed for three-terminal components. Confirm RoHS compliance status through current datasheets before integration into regulated assemblies.
Selection Notes
Select this component when board space constraints require an 0805 footprint but superior filtering performance compared to standard two-terminal capacitors is necessary. The three-terminal design offers improved high-frequency response. Verify that the circuit environment does not exceed the 25 VDC rating or the +125°C maximum operating temperature.
Part Context
This component belongs to the Knowles Syfer family of multi-layer ceramic capacitors. It is specifically engineered as an EMI filter rather than a general-purpose energy storage device. The three-terminal design distinguishes it from standard MLCCs by providing a grounded center electrode for effective noise shunting.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source data. Cross-referencing requires matching capacitance, voltage rating, package size, and three-terminal configuration.
