SMV1232-040LF

Overview

The SMV1232-040LF is a silicon hyperabrupt junction tuning varactor diode from the SMV123x series, manufactured by Skyworks Solutions Inc. It is housed in a single-channel SOD-882 surface-mount package with an inductance of 0.45 nH. The device supports a maximum reverse voltage of 15 V and operates within a temperature range of -55°C to +125°C. Electrical specifications include a typical capacitance of 1.50 pF at 3 V, a minimum breakdown voltage of 15 V, and a series resistance of 1.50 Ω at 3 V and 500 MHz.

Feature Summary

• Designed for low tuning voltage Voltage Controlled Oscillator (VCO) applications
• Optimized for high-Q resonators in wireless systems operating above 10 GHz
• Features low series resistance to support low phase noise performance

Applications

• Low tuning voltage VCOs
• High-Q resonators in wireless system VCOs
• High-volume commercial systems

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance and lead-free status via official documentation. Check Moisture Sensitivity Level (MSL1) handling requirements before soldering. Ensure storage conditions prevent moisture absorption prior to reflow assembly.

Selection Notes

Select this component for designs requiring a single-channel hyperabrupt varactor with low parasitic inductance. Verify that the 15 V reverse voltage rating meets circuit requirements. Compare series resistance values against other family members to ensure optimal phase noise performance for the specific frequency band.

Part Context

This part belongs to the SMV123x series of silicon hyperabrupt junction varactors. The series includes various packages such as SC-79, SOD-323, SOT-23, and SOD-882. The SMV1232 variant specifically targets applications needing moderate capacitance ratios and low series resistance for RF tuning.

Replacement Considerations

SMV1232-079LF shares identical electrical characteristics but utilizes the SC-79 package instead of SOD-882.
