Overview
The Knowles Syfer 0805J0500221MCTE01 is a three-terminal EMI filter capacitor in an 0805 (2012 metric) surface-mount package. It features a C0G/NP0 dielectric with a capacitance of 220 pF and a ±20% tolerance. The device is rated for 50 VDC and utilizes a nickel barrier with 100% tin termination system. 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 high-frequency EMI filtering performance compared to standard two-terminal capacitors.
- C0G/NP0 dielectric material ensures stable capacitance characteristics across varying temperatures and voltages.
- Nickel barrier and 100% tin termination system offers reliable solderability and corrosion resistance.
Applications
- High-frequency electromagnetic interference (EMI) suppression in sensitive electronic circuits.
- Signal integrity protection in communication equipment and data transmission lines.
- Noise filtering in automotive electronics requiring robust thermal stability.
Procurement Notes
Verify the specific suffix 'E01' against official datasheets to confirm the three-terminal configuration and terminal arrangement. Ensure compatibility with PCB pad layouts designed for three-terminal components. Confirm RoHS compliance status through current manufacturer documentation before integration into regulated products.
Selection Notes
Select this component when superior high-frequency attenuation is required in a compact 0805 footprint. The C0G dielectric makes it suitable for precision applications where capacitance drift must be minimized. Consider the three-terminal layout constraints during schematic capture and PCB design phases to ensure proper grounding and signal path isolation.
Part Context
This part belongs to the Knowles Syfer Syfer® family of MLCCs, specifically engineered for EMI filtering. The '0805J' prefix indicates the 0805 case size and voltage rating class, while '0500' denotes the 50V DC working voltage. The '221' code specifies the 220 pF capacitance value.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Cross-referencing requires matching three-terminal 0805 form factors with equivalent C0G dielectric properties and 50V ratings from other manufacturers.
