Overview
The Knowles Syfer 1806Y0250274MJTE07 is a surface-mount feed-through capacitor with an X7R dielectric. It features a capacitance of 0.27 µF, a voltage rating of 25 VDC, and a tolerance of ±20%. Designed in the 1806 (4516 metric) package, it supports a continuous current of 2 A and operates within a temperature range of -55°C to +125°C.
Feature Summary
- Three-terminal EMI filter architecture for effective noise suppression
- Feed-through design enabling direct signal path integration
- X7R ceramic dielectric providing stable capacitance characteristics
Applications
- High-frequency signal line filtering
- Power supply input/output decoupling
- EMI suppression in sensitive electronic circuits
Procurement Notes
Verify the specific suffix codes against official datasheets to confirm terminal configuration and termination material. Ensure the selected variant matches the required current rating and voltage derating for the target application environment. Cross-reference manufacturer part numbers to avoid substitution errors.
Selection Notes
Select this component when a three-terminal feed-through topology is required for superior high-frequency attenuation compared to standard two-terminal capacitors. The 1806 package offers a balance between footprint size and current handling capability. Verify that the 2 A current rating aligns with the maximum expected load current in the circuit design.
Part Context
This component belongs to the Knowles Syfer EMI Filter series, which specializes in multilayer ceramic feed-through capacitors. These devices are engineered for robust electromagnetic interference suppression in compact surface-mount designs, serving as critical passive components in modern high-density electronics.
Replacement Considerations
Direct replacements must match the 1806 package, 0.27 µF capacitance, 25 V rating, and three-terminal feed-through structure. Verify compatibility with existing PCB pad layouts due to the distinct terminal arrangement of feed-through capacitors.
