VEMI85AC-HGK-GS08

Overview

The VEMI85AC-HGK-GS08 is an RC (Pi) EMI filter manufactured by Vishay General Semiconductor - Diodes Division. It features eight channels with a resistance of 100 Ohms and capacitance of 13pF per channel. The device supports a current rating of 4 A and has a cutoff frequency of 240MHz. Packaged in a 16-UFDFN Exposed Pad, it operates within a temperature range of -40°C to 125°C.

Feature Summary

• Provides integrated EMI filtering and ESD protection for high-speed data lines
• Utilizes RC (Pi) topology for second-order low-pass filtering characteristics
• Offers multi-channel configuration suitable for complex interface requirements

Applications

• Data lines for mobile devices
• High-speed digital signal protection
• Portable electronic equipment interfaces

Procurement Notes

Verify the specific suffix HGK against official Vishay documentation to confirm pinout and electrical tolerances. Ensure the 16-UFDFN package dimensions match your PCB footprint constraints. Confirm RoHS3 compliance status through the latest datasheet revision before finalizing procurement specifications.

Selection Notes

Select this component when eight-channel protection is required for data lines operating at frequencies up to 240MHz. The 100 Ohm resistance value is critical for impedance matching in specific bus architectures. Consider the 4A current rating for power handling capabilities in active data transmission scenarios.

Part Context

This part belongs to the VEMI series of EMI filters from Vishay. These components are designed to suppress electromagnetic interference while protecting sensitive electronics from electrostatic discharge events. The series offers various channel counts and impedance values to suit different interface standards.

Replacement Considerations

VEMI85AB-HGK-GS08 is a documented alternative with 100 Ohm resistance but 24pF capacitance. Verify that the higher capacitance value does not degrade signal integrity in your specific application design.
