Procurement Notes
Verify current availability status directly with Microchip Technology or authorized distributors, as this item may be subject to special order constraints. Confirm RoHS compliance details and specific packaging configurations prior to procurement. Ensure that the hermetic seal integrity meets the required environmental standards for the intended application environment.
Selection Notes
Select the GC1611-85 when hermetic sealing is mandatory for the application. Consider its silicon varactor technology for stable capacitance variation. Evaluate the pill package dimensions against board space constraints. Verify that the voltage range and capacitance tuning requirements align with the circuit design specifications before finalizing the selection.
Part Context
This component belongs to Microchip Technology's discrete semiconductor portfolio, specifically within the varactor diode category. It complements the company's broader range of RF and analog components used in critical infrastructure and industrial applications. The part represents a specialized solution for tunable circuit elements requiring high durability.
Replacement Considerations
Consult official Microchip documentation for verified substitute part numbers. Cross-reference technical specifications such as capacitance range, breakdown voltage, and package dimensions to ensure functional equivalence. Generic replacements may not offer the same hermetic sealing quality.
