Procurement Notes

Verify the specific ordering suffix when sourcing this component. The base part number KVX2132-23-0 may be available in bulk packaging, while the KVX2132-23-0/TR variant specifically denotes tape-and-reel packaging. Confirm the required packaging format matches your assembly line equipment before finalizing procurement orders to ensure compatibility.

Selection Notes

Select this component based on its specific capacitance value of 4.2 pF at zero bias and its high Q-factor of 850 at 50MHz. Ensure the design accommodates the 22V peak reverse voltage limit and the wide operating temperature range from -55°C to 125°C. Verify that the SOT-23-3 footprint aligns with the PCB layout requirements for the target application.

Part Context

This device belongs to the KVX series of varactor diodes produced by Microchip Technology. These components are engineered for general-purpose diode applications requiring variable capacitance characteristics. The KVX2132-23-0 represents a specific capacitance profile within this family, distinguished by its single-diode configuration and standardized SOT-23-3 surface-mount packaging.

Replacement Considerations

Consult official Microchip documentation for verified substitute part numbers within the KVX series. Cross-reference specifications such as capacitance at 0V, Q-factor at 50MHz, and peak reverse voltage to ensure functional equivalence. Do not assume interchangeability with other manufacturers' varactors without validating all electrical parameters against the original datasheet.
