VEMI35AA-HAF-G-08

Overview

The VEMI35AA-HAF-G-08 is a third-order RC Pi-filter EMI filter with integrated ESD protection, manufactured by Vishay General Semiconductor. It features three channels with a resistance of 100 Ohms and capacitance of 37pF per channel. The device supports a maximum current of 4A and operates within a temperature range of -40°C to 125°C. Packaged in an LLP75 surface-mount format, it provides low-pass filtering for data lines.

Feature Summary

• Integrates EMI filtering and ESD protection in a single compact component
• Provides third-order low-pass filtering characteristics for signal integrity
• Supports high current handling up to 4A for robust data line protection

Applications

• Mobile device data lines
• High-speed interface protection
• General EMI suppression in portable electronics

Procurement Notes

Verify the specific suffix G-08 against the manufacturer's latest documentation to confirm package type and compliance status. Ensure the LLP75 footprint matches the design layout. Confirm availability as product lifecycles may change; check official Vishay sources for current production status before finalizing procurement plans.

Selection Notes

Select this component when both EMI attenuation and ESD protection are required on high-speed data lines. The 100 Ohm resistance and 37pF capacitance values determine the cutoff frequency and impedance matching. Consider the 4A current rating for power handling requirements and the LLP75 package size for space-constrained PCB designs.

Part Context

This part belongs to Vishay's VEMI series of RC Pi-filters designed for protecting sensitive electronic circuits from electromagnetic interference and electrostatic discharge events. These components consolidate multiple protection functions into a small surface-mount package, simplifying board layout and reducing component count in modern consumer electronics applications.

Replacement Considerations

Check Vishay datasheets for alternative parts within the VEMI series, such as VEMI353A-HAF-G-08 or VEMI255A-HS3-GS08, which offer different resistance values or channel counts. Verify that any substitute maintains the same LLP75 footprint and electrical specifications for direct replacement.
