Additional Details

The 2SC3478L is optimized for high-frequency, low-noise amplification. Key parameters include collector-emitter voltage (VCEO), collector current (IC), power dissipation (PC), and transition frequency (fT). Consult the official NEC (Renesas) datasheet for precise specifications to ensure compatibility with your application. It typically comes in a small signal package (e.g., SOT-23) designed for surface mount technology (SMT) assembly. The ‘L’ suffix likely signifies a specific gain or hFE range for the transistor.
