Характеристики транзистора c945

Где и как мы можем использовать ?

Максимальная нагрузка, которую может выдерживать этот транзистор, составляет около 150 мА, что достаточно для работы многих устройств в цепи, например реле, светодиодов и других элементов схемы. Напряжение насыщения Uкэ.нас. составляет всего 0.3 В, что также удовлетворяет почти все потребности. Как обсуждалось выше, C945 имеет хороший коэффициент усиления постоянного тока hFE и низкий уровень шума, благодаря чему он идеально подходит для использования в каскадах схем предусилителя, усилителя звука или для усиления других сигналов в электронных цепях. Напряжение насыщения большинства биполярных транзисторов составляет 0,6 В, но у нашего С945 Uкэ.нас. = 0,3 В, поэтому он может работать в цепях низкого напряжения.
