RF amplifiers, balanced mixers, and signal converters in communication equipment. Key Features:
Direct high-gain, low-noise functional Japanese equivalents designed for identical RF front-end systems.
The 3SK41 datasheet presents a specialized set of parameters designed for low-noise RF amplification and rapid switching. Below is the foundational technical framework of the component under standard test conditions ( Maximum / Typical Value Description 3sk41 datasheet
This is the core of the . These values assume a common-source amplifier configuration.
While a standard essay on a datasheet might sound dry, the "3sk41" is actually a fascinating subject because it sits at the precise intersection of consumer history and electronic obsolescence. The 3SK41 is not a modern microprocessor; it is a , a component that was once the beating heart of the VHF and UHF tuners in analog television sets.

The 3SK41 typically comes in a specialized 4-pin miniature plastic package (often designated as a variant of the TO-50 or a standard 4-pin RF lead frame). Because it is a high-frequency device, the pinout layout is designed to maximize isolation between the input and output.
Unfortunately, without access to a specific datasheet from a reliable source like a manufacturer or distributor, we can't provide detailed specifications here. However, typically, a datasheet for a JFET like the 3SK41 would include: Below is the foundational technical framework of the
The 3SK41 remains a classic, robust component for radio frequency applications. Its high transconductance, dual-gate capability, and low-noise characteristics make it a valuable transistor for sensitive RF amplification tasks.
The 3SK41 can be used in various applications, including:
(Note: A gate driver IC is essential to ensure the $V_GS$ threshold is met quickly to minimize switching losses in the linear region.)
4-pin package (Source, Gate 1, Gate 2, Drain). Typical Applications: VHF/UHF TV Tuner RF Amplifiers. High-frequency mixers. General-purpose high-frequency signal processing. Key Performance Metrics:
