Overview
The KVX2162-23-0/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 26 pF at 0 V and 1 MHz, with a quality factor of 400 measured 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 compact surface-mount designs
- High-quality factor performance at standard RF test conditions
- Extended industrial operating temperature range for harsh environments
Applications
- RF tuning circuits requiring variable capacitance
- Voltage-controlled oscillators (VCOs)
- Frequency modulation modules
Procurement Notes
Verify the specific suffix /TR indicates tape-and-reel packaging when ordering. Confirm the manufacturer part number KVX2162-23-0/TR matches the required SOT-23-3 footprint. Check current availability status as lead times may vary. Ensure compliance with RoHS3 directives if required by the target assembly process. Validate that the 22 V reverse voltage rating meets the circuit's peak reverse bias requirements.
Selection Notes
Select this component when a single varactor with moderate capacitance variation is needed in a small outline transistor package. Compare the 26 pF zero-bias capacitance against circuit requirements. Evaluate the Q value of 400 at 50 MHz for insertion loss considerations. Consider the -55°C to 125°C range for environmental suitability. Verify compatibility with automated pick-and-place equipment due to the reel packaging format.
Part Context
This device belongs to the KVX21xx series of varactor diodes from Microchip Technology. It shares the SOT-23-3 form factor with other variants like the KVX2152-23-0 and KVX2132-23-0, which offer different capacitance and Q-factor characteristics. The series is designed for general-purpose RF tuning applications where space constraints are critical.
Replacement Considerations
Direct substitutes within the same family include KVX2152-23-0/TR and KVX2132-23-0/TR, though their capacitance and Q values differ. Cross-manufacturer replacements require matching the SOT-23-3 package, 22 V reverse voltage, and similar C-V characteristics.
