Procurement Notes

Verify part authenticity through authorized Microchip distributors or direct channels. Confirm RoHS3 compliance and REACH status prior to procurement. Check for recent Product Change Notifications regarding packaging or assembly site updates. Ensure storage conditions adhere to MSL Level 1 requirements to maintain component integrity before soldering.

Selection Notes

Select this component when a single varactor with 22 V reverse voltage rating is required in an SOT-23-3 footprint. Compare capacitance values at specific bias voltages against circuit design specifications. Consider the Q-factor at target operating frequencies to ensure minimal signal loss. Verify thermal compatibility with the application's operational temperature range.

Part Context

This device belongs to the KVX2001-KVX3901A series of varactor diodes from Microchip Technology. The series offers various capacitance ranges while maintaining consistent packaging and voltage ratings.
