The HVU202ATRU-E is a variable capacitance diode — a varactor — from the * series, designed for voltage-controlled tuning in RF circuits. Its capacitance changes with the applied reverse bias, making it the core tuning element in VCOs, phase-locked loops, and filter banks where a DC voltage sets the operating frequency. The part is and carries ROHS3 compliance, so it fits lead-free assembly lines without a waiver.
For a BOM planner, that removes the urgency to stockpile or qualify a substitute. The ROHS3 compliance is current and covers the European RoHS recast, so no exemption expiry to track.
Because the HVU202ATRU-E is an active varactor with no declared second source in the record, the supply chain is tied to the original manufacturer. We source it through independent distribution channels and quote it to order against an RFQ. If your BOM needs a dual-source hedge, let us know the target capacitance range and package preference; we can search the * family for a drop-in alternative.
