The h FE linearity from 0.5A to 10A is excellent for this type, minimizing crossover distortion. The f T of 15-20 MHz is ideal for audio (20Hz-20kHz), providing enough gain bandwidth for stability without risking parasitic RF oscillations when properly laid out. If you cannot find the original D998/B778, several

Setelah mengganti ke persamaan (misal ke C5200/A1943), arus bias mungkin berubah. The f T of 15-20 MHz is ideal

. These silicon-based components are designed to work in perfect harmony, often found at the heart of mid-range audio amplifiers where they act as the "muscle" driving the speakers. The Role of the Pair In the world of electronics, these two are complementary pairs
