3sk41 — Datasheet

In RF receivers, one gate can be used for the signal input while the second gate handles an AGC voltage. This allows the circuit to dynamically adjust gain based on signal strength without detuning the input. Mixing Capabilities:

A complete datasheet PDF is not widely available for this vintage component. The information above represents the most reliable compilation of the device’s parameters from various component databases and service manuals.

Finding an original 3SK41 can be challenging outside of specialized "New Old Stock" (NOS) electronics vendors like Jotrin Electronics , UTSOURCE , or LittleDiode. If you need a functional substitute for a repair or layout emulation, look into these common alternative components: In RF receivers, one gate can be used

Often tied together to provide grounding and shielding. Drain (D): The output lead.

The Kenwood TS‑520S uses a 3SK41(L) as the RF mixer Q1, where it converts the incoming signal from 1.8 to 28 MHz to the intermediate frequency. It is also found as Q9 on the Noise Blanker board in the same transceiver, where it helps suppress impulse noise. The Kenwood TS‑820 and TS‑830S are other examples of hybrids that incorporate the 3SK41 in the RF unit. Share public link Do you need help verifying a specific
