3sk41 Datasheet Link

Typically used for AGC or as the local oscillator input in mixers. Gate 1 (G1): The primary signal input lead.

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. 3sk41 datasheet

Often tied together to provide grounding and shielding. Drain (D): The output lead. Typically used for AGC or as the local

Minimizes loading on preceding stages. 2. Technical Specifications (Absolute Maximum Ratings) If you cannot find an original, consider these

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.

Facilitates easy Automatic Gain Control (AGC) and mixing functions.
