WebhFE (cũng được gọi là β - beta) là hệ số khuếch đại theo đó dòng điện ở cực gốc chuyển thành dòng điện khuếch đại. Dòng khuếch đại này sẽ đi qua các cực thu và cực phát của transistor. Transistor hoạt động bằng cách cho một dòng điện vào cực gốc. Dòng điện ở cực gốc sau đó được khuếch đại theo hệ số hFE để tạo thành dòng khuếch đại. Web18 de mai. de 2024 · The BC107 is a small single NPN Transistor available in TO-18 metal can package. These transistors are age old and have been used in low noise and low signal designs. Today a lot new transistors have come as replacement for BC107, but still the transistor can be found in market for its legacy. Pin Configuration Features Small …

Therefore it's equivalent circuit represents a current amplifier at the output section. hoe is the conductance of the output. So 1/hoe is the resistance parallel to it. More the value of 1/hoe, better is the current source. So for a good transistor the value of hoe is very small. fnf bambi art
