Product Details

BF234 RF Transistor - Stable Amplification for IF/RF Stages

The BF234 is an NPN silicon RF transistor housed in a TO-106 package, purpose-built for small-signal amplification at high frequencies. It is a common choice in the IF (intermediate frequency) amplifier stages of AM/FM radio receivers and other RF tuner circuits, where its high transition frequency and low collector capacitance keep the signal clean with minimal losses.

Functions & Applications

High Transition Frequency (ft): Around 250MHz, suitable for RF and IF amplification stages.
Low Collector Capacitance: Minimizes signal loss and distortion at high frequencies.
TO-106 Package: Compact plastic through-hole case, easy to fit in vintage and modern receiver PCBs.
Reliable Silicon Construction: Stable gain and performance across a wide temperature range.
Ideal for IF Amplifiers: Commonly used in AM/FM tuner and telecommunications equipment.

Frequently Asked Questions

Q: What is the BF234 used for?
A: It is designed for RF and IF small-signal amplification, most commonly in the intermediate frequency stages of AM/FM radio receivers and tuner circuits.

Q: Can the BF234 be used for general-purpose switching like a BC547?
A: It can technically switch small loads within its 30mA/30V rating, but it is optimized for RF gain and frequency response rather than general-purpose switching, so a BC547 is a better fit for that role.

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