KVX2162-23-0

Overview

The KVX2162-23-0 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 RoHS compliant, classified under EAR99, and has a moisture sensitivity level of 1.

Feature Summary

• Single-channel varactor configuration optimized for compact surface-mount integration
• Wide operating temperature range suitable for demanding environmental conditions
• Non-hermetic plastic construction for cost-effective manufacturing

Applications

• Voltage-controlled oscillator (VCO) tuning circuits
• Frequency modulation (FM) modulators
• Phase-locked loop (PLL) filter networks

Procurement Notes

Verify the specific ordering suffix against official Microchip documentation to ensure correct packaging and tape-and-reel specifications. Confirm that the requested variant matches the required RoHS compliance status and moisture sensitivity level before finalizing procurement orders to avoid supply chain discrepancies.

Selection Notes

Select this component when a single-ended varactor with a 22 V reverse voltage rating is required in an SOT-23-3 footprint. Ensure the application circuit operates within the specified -55°C to +125°C temperature range and accounts for the 26 pF baseline capacitance at zero bias for proper frequency planning.

Part Context

This part belongs to the KVX series of varactor diodes from Microchip Technology, which are commonly used in RF and microwave tuning applications. The series offers various capacitance ratios and voltage ratings to suit different oscillator and filter designs, providing designers with flexible options for frequency control in communication systems.

Replacement Considerations

Consult Microchip's official substitution guide or datasheet cross-reference section for verified equivalent parts. Do not assume functional compatibility with other manufacturers' varactors without verifying pinout, capacitance-voltage characteristics, and package dimensions.
