Procurement Notes

Verify the specific suffix HGK against official Vishay documentation to confirm pinout and marking codes. Ensure the 16-UFDFN footprint matches your PCB design requirements. Confirm RoHS3 compliance status through the latest datasheet revision. Cross-reference the manufacturer part number with authorized distributor catalogs to avoid counterfeit components. Check for any recent product change notices affecting assembly or sourcing locations.

Selection Notes

Select this component when a dual-channel low-pass filter is required for data lines with a 100 Ohm impedance profile. The 24pF capacitance value is critical for maintaining signal integrity at specific cutoff frequencies. Consider the 16-UFDFN package size for space-constrained applications. Evaluate the 4A current rating against peak operational loads. Compare thermal performance characteristics if operating near the upper temperature limit.
