VEMI45AC-HNH-GS08

Overview

The VEMI45AC-HNH-GS08 is a second-order low-pass EMI/RFI filter utilizing RC (Pi) network technology. It features four channels with a cutoff frequency of 240MHz, rated for 2A current. Each channel integrates a 100 Ohm resistor and a 13pF capacitor. The component includes integrated ESD protection and operates within a temperature range of -40°C to 125°C. It is housed in an 8-UFDFN package with exposed pads, measuring 1.70mm x 1.35mm x 0.60mm.

Feature Summary

• Integrates RC Pi-filter topology for effective noise suppression
• Provides built-in electrostatic discharge protection
• Supports high-speed data line filtering applications

Applications

• Mobile device data lines
• High-speed interface signal conditioning
• Portable electronics EMI mitigation

Procurement Notes

Verify the specific suffix GS08 against manufacturer documentation to confirm RoHS compliance and material composition. Confirm package orientation and pin 1 identification markings on the 8-UFDFN footprint. Check for any recent Product Change Notifications regarding manufacturing location or material updates before finalizing procurement specifications.

Selection Notes

Select this component when designing circuits requiring simultaneous EMI filtering and ESD protection for multiple high-speed data lines. Ensure the 100 Ohm series resistance aligns with the target impedance requirements of the connected interfaces. Verify that the 240MHz cutoff frequency adequately attenuates the specific noise spectrum while preserving signal integrity for the intended data rate.
