BF183 NPN UHF Transistor – Classic RF Performance for Tuners & Oscillators

The BF183 is a heritage NPN silicon transistor designed for high-frequency oscillator and RF amplifier circuits, particularly in television tuner applications. With its TO-72 metal can package offering superior shielding, the BF183 provides stable performance at UHF frequencies and remains an essential component for restoring vintage electronics and building authentic RF circuits.

Functions & Applications

UHF Optimized: Designed for stable oscillator and RF amplifier performance in the UHF band.
Metal Can Package: TO-72 case with integral shield, critical for reducing parasitic oscillation and noise at high frequencies.
Silicon Stability: Overcomes the thermal drift and reliability issues of earlier germanium designs.
Vintage-Ready: Authentic choice for restoring 1970s–1980s television tuners and classic RF equipment.

Frequently Asked Questions

Q: Why must the case be grounded?
A: At UHF frequencies, the metal case (4th pin) acts as an RF shield. Grounding it suppresses parasitic oscillation and maintains circuit stability—essential for tuner oscillators and RF amplifiers.

Q: Can the BF183 be used in modern VHF/UHF projects?
A: Yes. While designed for 1970s–1980s applications, the BF183 remains suitable for vintage restorations and RF hobby circuits requiring authentic behavior. For new designs, consider modern low-noise RF transistors.

Notes

Heritage UHF transistor; widely used in vintage 1970s–1980s television tuners. The TO-72 metal can with integral shield is integral to the design and must be properly grounded for correct operation at UHF frequencies.
