Overview
The Knowles Syfer 0805J1000272MXTE01 is a 2700 pF feed-through capacitor rated for 100 VDC. It utilizes an X7R dielectric with a ±20% tolerance, housed in an 0805 (2012 metric) package. The component features a three-terminal SMD/SMT configuration with a current rating of 300 mA. Operating temperatures range from -55°C to +125°C.
Feature Summary
- Three-terminal feed-through architecture for enhanced EMI filtering
- X7R ceramic dielectric for stable capacitance characteristics
- SMD/SMT termination compatible with standard assembly processes
Applications
- EMI suppression in high-frequency circuits
- Power line filtering for sensitive electronics
- Signal integrity protection in communication modules
Procurement Notes
Verify the specific suffix MXTE01 against official datasheets to confirm terminal plating and packaging details. Ensure compatibility with PCB footprint dimensions for three-terminal components. Cross-reference manufacturer part numbers to avoid substitution errors with similar two-terminal MLCCs.
Selection Notes
Select this component when EMI filtering is required in space-constrained designs. The three-terminal structure offers superior high-frequency performance compared to standard capacitors. Verify that the 300 mA current rating meets circuit requirements and that the X7R temperature coefficient aligns with operational conditions.
Part Context
This component belongs to the Knowles Syfer feed-through capacitor series. These devices integrate filtering capabilities directly into the package structure. The three-terminal design provides lower parasitic inductance than conventional two-terminal capacitors, making them suitable for high-speed digital and RF applications requiring robust noise suppression.
Replacement Considerations
Substitute only with verified three-terminal feed-through capacitors of identical voltage and capacitance ratings. Confirm package dimensions match the existing PCB footprint. Two-terminal MLCCs are not direct replacements due to differing filtering performance and mounting requirements.
