Whether you are repairing a classic ICOM receiver, building a low-noise preamplifier for an SDR, or simply satisfying your curiosity about dual-gate MOSFETs, understanding the 3SK41’s pinout (TO-72), biasing (VG2 = 4V typical), and limitations (200mW, 30mA) is essential.
Standard range (e.g., up to 125°C or higher for metal cans) Feature Look-In: The Dual-Gate Advantage The defining characteristic of the 3SK41 is its 3sk41 datasheet
): Extremely low (approx. 0.02 pF), which is vital for stability in high-frequency amplifiers. Typically 2.0 to 3.0 dB at 200 MHz. 4. Pinout Configuration Whether you are repairing a classic ICOM receiver,
A universal replacement part often found in repair catalogs. ⚠️ Usage Considerations understanding the 3SK41’s pinout (TO-72)
