VEMI353A-HAF-G-08

Overview

The VEMI353A-HAF-G-08 is a surface-mount RC Pi-filter EMI/RFI suppression component manufactured by Vishay General Semiconductor. It features three channels with a resistance of 30 Ohms and capacitance of 37 pF per channel. The device supports a peak current of 4 A and operates within a temperature range of -40°C to 125°C. Housed in a 6-UFDFN package with an exposed pad, it provides low-pass filtering for data lines.

Feature Summary

• Integrates RC Pi-filter topology for effective EMI and RFI suppression
• Provides multi-channel protection for high-speed data lines
• Designed for compact surface-mount applications

Applications

• ESD protection for mobile device data lines
• EMI filtering in portable electronics
• Signal integrity enhancement in USB or similar interfaces

Procurement Notes

Verify the complete part number including suffixes against official Vishay documentation to ensure correct packaging and specifications. Confirm RoHS compliance status and lead-free characteristics as required by your manufacturing standards. Cross-reference the supplier datasheet for accurate handling and storage conditions.

Selection Notes

Select this component when integrated EMI filtering and ESD protection are required for multiple data lines in space-constrained designs. The 30 Ohm resistance and 37 pF capacitance values are suitable for specific signal frequencies. Ensure the 6-UFDFN package footprint matches the PCB layout requirements.

Part Context

This component belongs to Vishay's VEMI series of EMI filters. It is designed specifically for suppressing electromagnetic interference in sensitive electronic circuits. The integration of resistive and capacitive elements into a single SMD package simplifies board design compared to discrete components.

Replacement Considerations

Consult Vishay technical support for verified alternative part numbers. Do not substitute with generic RC filters without verifying impedance and capacitance matching.
