It is an option on the multimeter, I have read a little bit saying it has to do with transistors and it is a "test" for it...
hFE stands for "DC current gain" and it is a measure of the amplification of current in a transistor. It is measured on a multimeter by placing the transistor in the appropriate socket and selecting the hFE function on the meter.
hFE is important because it determines the current amplification and switching capabilities of a transistor, which is a crucial component in many electronic circuits. It helps in selecting the right transistor for a specific application.
hFE is directly proportional to the gain of a transistor. This means that as hFE increases, the gain of the transistor also increases. This is because hFE measures the current amplification of the transistor.
A typical hFE value for a common transistor can range from 20 to 1000, depending on the type of transistor. However, it is important to note that the hFE value can vary greatly between individual transistors even of the same type.
Yes, hFE can be used as an indicator of the health of a transistor. A significantly lower or higher hFE value than the typical range for a specific type of transistor may indicate a faulty or damaged transistor. However, other tests may also be needed to confirm the health of a transistor.
