22 transistor types in labeled plastic reel for quick access. Organized storage saves time during prototyping/repairs.
SOT-23 footprint works with standard soldering tools. No special handling needed—directly integrate into PCBs, breakout boards, or breadboards.
Supports power management, signal amplification, LED driving, motor control, and IoT projects. Ideal for Arduino/Raspberry Pi builds, power adapters, and automotive electronics.
Bulk Savings & Convenience.Save more vs. single purchases. Pre-sorted, labeled parts reduce sorting time. Ideal for bulk prototyping, small-batch manufacturing, or restocking.
