Frequently Asked Questions

Q: Is the 2SC1047 suitable for RF receiver front-end amplification?
A: Yes, the 2SC1047 is specifically designed for VHF/UHF small-signal RF applications. It performs well as a low-noise preamplifier stage in radio receiver circuits.

Q: What is the maximum frequency range for this transistor?
A: The 2SC1047 is optimized for VHF (30–300 MHz) and lower UHF bands. Performance gradually rolls off at higher frequencies due to parasitic capacitances.

Notes

Vintage and NOS (New Old Stock) parts may exhibit wide tolerance variation in hFE and frequency response; test and bin if precision matching is required.
