VEMI65AB-HCI-GS08

Overview

The VEMI65AB-HCI-GS08 is a surface-mount RC Pi-filter EMI/RFI suppression component manufactured by Vishay General Semiconductor - Diodes Division. It features a second-order low-pass filter configuration with six channels, designed for high-density applications. The device integrates resistors of 100 Ohms and capacitors of 24pF per channel to provide effective noise attenuation. It operates within a temperature range of -40°C to 125°C and is housed in a compact 13-UFDFN package with an exposed pad, ensuring reliable performance in sensitive electronic circuits.

Feature Summary

• Integrates a second-order low-pass RC Pi-filter topology for enhanced EMI/RFI suppression
• Provides multi-channel filtering capability with six independent signal paths
• Utilizes a compact surface-mount package design suitable for space-constrained PCB layouts

Applications

• High-speed data line protection in portable electronics
• EMI suppression for USB and HDMI interfaces
• Signal integrity enhancement in mobile communication devices

Procurement Notes

Verify the specific suffix HCIGS08 against the manufacturer's current datasheet to confirm the exact capacitance value (24pF) and resistor tolerance. Ensure the ordering information matches the required package variant and compliance standards such as RoHS3 before finalizing procurement orders.

Selection Notes

Select this component when multiple differential or single-ended lines require simultaneous EMI filtering in a minimal footprint. The integrated RC structure simplifies board layout compared to discrete components. Verify that the 100 Ohm resistance and 24pF capacitance values align with the target frequency cutoff requirements for the specific application interface.

Part Context

This part belongs to the VEMI65 series of EMI filters from Vishay. It is distinct from other Vishay diode products like the BAS286 or TVS diodes listed in general catalogs. The VEMI series focuses on passive signal conditioning rather than active clamping or rectification, serving a different role in circuit protection strategies.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Consult the manufacturer's official substitution guide or equivalent technical specifications from other vendors for compatible alternatives.
