MAVR-000405-0287FT

Overview

The MAVR-000405-0287FT is a surface mount hyperabrupt junction silicon tuning varactor from the MAVR-000400 Series, manufactured by MACOM Technology Solutions. It is housed in an SOT-23 package and features ion-implanted construction with thermal oxide passivation. The device operates as a common cathode pair configuration. Key electrical specifications include a nominal total capacitance of 22 pF at 4 V reverse bias, a typical capacitance ratio of 7.5 (measured between 4 V and 20 V), and a minimum quality factor of 175 at 50 MHz. The component supports a maximum reverse voltage of 30 V and is supplied with 100% matte tin plating.

Feature Summary

• Ion-implanted hyperabrupt junction design for high capacitance ratio and quality factor
• Common cathode pair configuration within a compact SOT-23 surface mount package
• SPC monitored ion implantation process ensuring excellent C-V repeatability
• RoHS compliant construction with 100% matte tin plating

Applications

• Voltage controlled oscillators (VCOs) requiring octave bandwidth tuning
• Voltage tuned filters in radio frequency systems
• Cable TV tuners and test instruments demanding lot-to-lot consistency

Procurement Notes

Verify that the ordering suffix corresponds to the specific package style, configuration, and packaging requirements defined by the manufacturer. Confirm RoHS compliance status and matte tin plating specifications against current datasheet revisions before procurement. Ensure handling procedures account for electrostatic discharge sensitivity during storage and assembly.

Selection Notes

Select this component when a common cathode configuration is required for HF to UHF tuning applications. The 22 pF nominal capacitance and 7.5 capacitance ratio suit designs needing moderate tuning ranges. Verify that the SOT-23 footprint aligns with the PCB layout constraints and that the operating temperature range meets the system's environmental requirements.

Part Context

This part belongs to the MAVR-000400 Series of surface mount hyperabrupt varactors. The series includes single diode variants and other capacitance values. The 'FT' suffix specifically denotes the common cathode pair configuration and tape and reel packaging, distinguishing it from the 'AT' single diode variants within the same family.

Replacement Considerations

Direct substitutes within the MAVR-000400 series include MAVR-000405-0287AT for single diode applications, though pinout configurations differ. Cross-series replacements require matching capacitance, Q factor, and package dimensions.
