Product Details

BF214 Shielded RF Transistor – Premium IF Amplification for Radio Receivers

The BF214 is a shielded NPN RF transistor specifically engineered for intermediate frequency amplification in radio receivers. Its metal shield and dedicated grounding lead eliminate capacitive coupling noise, making it the preferred choice for restoring vintage 1970s receivers and precision RF circuits where signal integrity is paramount.

Functions & Applications

Integrated Metal Shield: Dedicated 4th lead provides grounding of the metal shell, eliminating RF coupling noise and EMI interference.
IF Stage Optimized: Engineered for stable performance in intermediate frequency amplification stages of radio receivers.
Vintage-Friendly: Ideal for restoring and rebuilding 1970s radio equipment without requiring redesign.
Silicon Stability: Superior temperature stability and reliability compared to older germanium RF designs.

Frequently Asked Questions

Q: Can BF214 replace germanium RF transistors in vintage radios?
A: Yes, but the base bias resistors must be recalculated. Silicon has Vbe ≈ 0.7V while germanium is ≈ 0.2V, requiring adjusted biasing for proper operating point.

Q: Why does BF214 have a 4th lead if most transistors have only 3?
A: The 4th lead connects the metal shield to ground, isolating the transistor from external RF noise and EMI—essential for clean IF amplification.

Notes

Vintage RF transistor with integrated shielding. Requires careful handling of the 4th shield lead; proper grounding is critical for noise performance. Ideal for radio restoration projects.

Note: Price refers to one (1) piece. The component is shipped in bulk without individual packaging.
