1812Y0500125MXTE07

Overview

The Knowles Syfer 1812Y0500125MXTE07 is a feed-through capacitor with a capacitance of 1.2 µF and a DC voltage rating of 50 VDC. It utilizes C0G/NP0 dielectric material for stable performance across temperatures ranging from -55°C to +125°C. The component features a 1812 (4532 metric) surface-mount package and supports a current rating of 2 A. Designed for high-frequency applications, it integrates shielding within the structure to minimize electromagnetic interference.

Feature Summary

• Integrated feed-through architecture provides inherent shielding against electromagnetic interference
• C0G/NP0 dielectric ensures minimal capacitance variation over temperature and voltage changes
• High current handling capability suitable for power line filtering applications

Applications

• High-frequency noise suppression in sensitive electronic circuits
• Power supply input filtering for RF modules
• EMI reduction in automotive infotainment systems

Procurement Notes

Verify the specific suffix E07 against the manufacturer datasheet to confirm tape-and-reel specifications and quantity per reel. Ensure compatibility with standard reflow soldering profiles for feed-through components. Confirm RoHS compliance status through official environmental declarations prior to integration into regulated assemblies.

Selection Notes

Select this component when board space constraints require a compact solution for high-current filtering. The 1812 footprint offers a balance between current capacity and size. Consider the C0G stability if circuit performance must remain consistent under varying thermal conditions or bias voltages compared to X7R alternatives.

Part Context

This part belongs to the Knowles Syfer FlexiCap series, which emphasizes reliability in harsh environments. Feed-through capacitors differ from standard MLCCs by integrating the ground connection directly through the component body, reducing parasitic inductance significantly. This design is critical for maintaining signal integrity in high-speed digital and RF applications.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify pinout and dimensional compatibility before considering alternative manufacturers' feed-through capacitors.
