C1124 Transistor Datasheet — Better ((full))

Search for "2SC1124" and download the OCR-processed version. You can copy-paste text from it—that is a "better" experience.

The C1124 is a mediocre 30V, 100mA RF part by today's standards. Its only legacy is its specific TO-126 footprint and 250MHz cutoff. Any modern transistor with >30V, >100mA, and >200MHz fT will work. c1124 transistor datasheet better
