Description

BC846-QR is a small-signal NPN transistor in the BC846 family, typically used for general-purpose amplification and switching in compact circuits. The “QR” suffix usually denotes a particular vendor’s RoHS-compliant, reliability-tested variant; exact electricals can vary, so always consult the specific datasheet for the lot you have.
Typical characteristics (variant dependent):
- Package: SOT-23
- Ic: up to about 100 mA
- Vceo: ~45 V (varies by part)
- Gain (hFE): ~110–800 depending on grade (A/B/C)
- Low-noise, suitable for signal amplification
Pinout (common SOT-23 BC846): 1 = Emitter, 2 = Base, 3 = Collector (with the flat face toward you; verify from your manufacturer).
Common uses: preamplifiers, switching in low-power analog/digital circuits, small-signal amplification in consumer electronics.
Note: for exact values and pinout, check the specific BC846-QR datasheet from the vendor.
