Overview
The KVX2132-23-0/TR is a single-path varactor diode manufactured by Microchip Technology, designed for surface-mount applications in the SOT-23-3 package. It features a maximum peak reverse voltage of 22 V and operates within a temperature range of -55°C to 125°C. Key electrical parameters include a capacitance of 4.2 pF at 0 V and 1 MHz, and a quality factor of 850 at 4 V and 50 MHz. The component is supplied in tape and reel packaging and complies with RoHS3 standards.
Feature Summary
- Single-channel varactor configuration optimized for RF tuning circuits
- High quality factor performance at standard test frequencies
- Extended industrial operating temperature range for harsh environments
- Surface-mount SOT-23-3 package for automated assembly
Applications
- RF filter tuning networks
- Voltage-controlled oscillator (VCO) circuits
- Frequency modulation modules
Procurement Notes
Verify the specific suffix -TR indicates tape and reel packaging when ordering. Confirm the manufacturer part number KVX2132-23-0/TR matches the required SOT-23-3 footprint. Check current availability status as distribution channels may vary. Ensure compliance with RoHS3 requirements for the target assembly process.
Selection Notes
Select this component based on the required 4.2 pF zero-bias capacitance and 22 V reverse voltage rating. Compare the Q value of 850 at 4 V/50 MHz against circuit sensitivity requirements. Consider the SOT-23-3 package constraints for PCB layout. Verify thermal limits align with the -55°C to 125°C operational range.
Part Context
This device belongs to the KVX2xxx series of varactor diodes from Microchip Technology. It shares the same basic KVX2132 product identifier but differs in packaging and quantity configurations compared to bulk or cut-tape variants. The series is characterized by silicon TVAR technology for general-purpose diode applications.
Replacement Considerations
Direct substitutes within the same family include KVX2132-23-0/DKR for cut-tape and KVX2132-23-0/CT for cut tape. Verify pinout compatibility and electrical parameter tolerances before substituting with other varactor brands.
