3sk41 Datasheet Jun 2026

The 3SK41 remains a respected component for RF enthusiasts due to its low noise and stable gain. Whether you are repairing a vintage transceiver or building a custom VHF pre-amplifier, understanding the is the first step toward a successful build. Always ensure proper ESD (Electrostatic Discharge) precautions when handling these MOSFETs, as the gates are highly sensitive to static electricity.

The specifications provided are aggregated from historical sources. Always refer to an original manufacturer datasheet for critical design validation. This article is for educational purposes. The 3SK41 remains a respected component for RF

Because the 3SK41 is an older component, it can sometimes be difficult to source. If you cannot find an original, consider these common substitutes: Very similar characteristics, often interchangeable. Acting as the first stage of amplification
