SMV1771-040LF

Overview

The SMV1771-040LF is a single varactor diode manufactured by Skyworks Solutions, Inc., housed in an SOD-882 surface-mount package. It features a series inductance (Ls) of 0.45 nH and supports a maximum reverse voltage (Vr) of 15 V with a forward current (If) rating of 20 mA. The device operates within a temperature range of -55°C to +125°C. This component is classified as End-of-Life (EOL), with official discontinuation notifications dated April 29, 2026, and May 15, 2026.

Feature Summary

• Single configuration varactor diode designed for RF applications
• Integrated low series inductance for high-frequency performance
• RoHS compliant construction suitable for lead-free assembly

Applications

• RF tuning circuits
• Voltage-controlled oscillators (VCOs)
• Phase-locked loops (PLLs)

Procurement Notes

This component has reached its end-of-life stage. Official discontinuation notifications from the manufacturer are dated April 29, 2026, and May 15, 2026. Procurement should be limited to existing surplus stock or last-time buys, as new production will cease. Verify authenticity and storage conditions carefully due to the age of available inventory.

Selection Notes

Designers requiring this specific capacitance profile must account for the EOL status when planning long-term production. Evaluate alternative components from the same manufacturer family or other suppliers that offer similar electrical characteristics and package dimensions to ensure future supply chain stability.
