RN1544
TOSHIBA Transistor Silicon NPN Epitaxial Type (PCT process) (Bias Resistor built-in Transistor)
RN1544
For use in Muting and Switching Applications.
* * Emitter-base voltage is high: VEBO = 25 V (max) Incorporating a bias resistor into a transistor reduces parts count. Reducing the parts count enable the manufacture of ever more compact equipment and save assembly cost. Unit: mm
