luxury transistor tester

6-14 — elektor june 1980 luxury transistortester This particular design first appeared on Elektor"s pages in last year"s Summer Circuits issue. Readers voted it as one of the most interesting circuits and this article is the elected Elektorised result. The circuit has been slightly modified and a printed circuit board now accompanies it. In technical literature, the current amplification is usually indicated as hFE. For everyday purposes it is not absol- utely necessary to know the precise hFE value, but rather to have a rough idea of its upper and lower limits. The manufac- luxury tester A highly important aspect of transistors is their current amplification ratio. This is often indicated by an A, B, or C behind the type number in the case of transistors. Inevitably however (by decree of Murphy himself), this is no longer legible. Using the transistor tester described here, the correct letter can be read from a display. At the same time, it can also be determined whether the tr...
