BC108 family : ウィキペディア英語版 | BC108 family The BC107, BC108 and BC109 are general purpose low power Silicon NPN bipolar junction transistors found very often in equipment and electronics books/articles from Europe, Australia and many other countries. They were created by Philips and Mullard in 1963 and introduced in April 1966. Initially in metal (TO-18) packages, the range expanded over time to include other package types, higher voltage ratings, and a better selection of gain (hFE and hfe) groupings, as well as complementary PNP types. Some manufacturers have specified their parts with a higher power dissipation rating (Ptot) than others. The BC548 is an example of the modern low-cost member of this family, still in a through-hole package, while the BC848 is the Surface-mount version. ==Table of BC107 to BC860 Variants==
(see also: () for a neat summary of some of the family). Noise Figure (at 1kHz, for 2 kilohm source, BW=200Hz, IC=0.2mA/VCE=5V) is <10dB for those not tabulated as "Low Noise".
