3sk41 Datasheet [updated] Link

Provides significant amplification in the RF stage to improve receiver sensitivity. Common Applications & Use Cases

), eliminating the "Miller Effect" that routinely destabilizes single-gate transistors at high frequencies.

In the 1970s and 80s, components like the 3SK41 were the "brain" behind the clear signal reception of color televisions and high-fidelity FM radios. Obsolescence: 3sk41 datasheet

) and excellent high-frequency characteristics, the 3SK41 is not built for high-power conversion; instead, it thrives in precise signal environments:

To help me provide more specific information, could you tell me: Provides significant amplification in the RF stage to

A highly accessible, surface-mount (SOT-143) N-channel dual-gate MOSFET offering high transconductance and low noise. It is widely used to replace vintage through-hole RF FETs.

are often recommended for their similar low-noise performance. www.jotrin.ru Quick Specs Summary Description Silicon (Si) Configuration Dual-Gate (for AGC/Mixing) Typically CAN-4 or similar through-hole Current Life Obsolete / Hard-to-find for this part, or are you looking for a specific supplier to buy one? 3SK41 - NEC/HITACHI/MOTOROLA - Jotrin Electronics I can suggest specialized distributors.
