Frequently Asked Questions

Q: What is the maximum voltage the BC172 can handle?
A: The BC172 has a Vceo rating of 25V, so it should only be used in circuits operating below this collector-emitter voltage.

Q: Is the BC172 suitable for audio applications?
A: Yes, it's commonly used in low-noise audio preamplifier stages and small-signal processing circuits due to its clean gain characteristics.

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