Description
The 2SA1266 is a versatile PNP bipolar junction transistor known for its excellent performance in general-purpose amplification and switching applications. With a robust DC current gain (hFE) ranging from 70 to 400, this transistor provides the high sensitivity and amplification required for diverse signal-processing tasks, including audio pre-amplification and low-power driver stages.
Designed to handle a collector current of up to 150 mA, the 2SA1266 is an efficient solution for small-signal circuit designs. Its wide storage temperature range (-55°C to +150°C) and maximum junction temperature of 150°C ensure reliable operation in varied thermal conditions. This pack of 15 units is a cost-effective choice for hobbyists, educational projects, and professional electronics technicians maintaining or developing small-signal hardware.
