Working on an electronics project or repairing audio gear? This is a bulk pack of 500 BC556B transistors. These are general-purpose PNP bipolar junction transistors, rated for 65 volts and 0.1 amps. They're super common in analog circuits, especially in audio preamps, signal processing, and various low-power switching applications. Having a big bag of these is perfect for hobbyists, students, or repair technicians. You'll always have spares on hand for prototyping or fixes. They're unbranded but sold as original components, brand new in their packaging. The MPN is BC556B. If your schematic calls for a BC556, BC556A, or BC556B, this will do the job (the 'B' suffix indicates a higher gain version). A must-have staple for any well-stocked electronics workbench. Don't get stuck waiting for parts—grab this value pack and keep building!
