Procurement Notes
Verify the manufacturer designation and component type against official datasheets before procurement. Confirm that the specific ordering suffix matches the required reel size and tape width specifications. Ensure compliance with RoHS directives and check for any discontinuation notices or lifecycle status updates directly from the supplier.
Selection Notes
Select this component based on its hyperabrupt junction profile suitable for wide tuning ranges. Evaluate the capacitance tolerance and Q factor requirements against the circuit's phase noise sensitivity. Verify that the operating temperature range and power dissipation limits align with the intended application environment and thermal constraints.
Part Context
This part belongs to the ZC930, ZMV930, and ZV931 series of silicon 12V hyperabrupt varactor diodes. These devices are available in single or dual common cathode formats within miniature surface mount packages including SOT23, SOD323, and SOD523. The series is engineered for low reverse current to ensure minimal phase noise in frequency control circuits.
