9014 TRANSISTOR NPN SMALL SIGNAL TRANSISTOR CDIL 9014

Product Overview:

A through-hole NPN silicon epitaxial planar small-signal bipolar junction transistor housed in a standard TO-92 plastic package. Engineered specifically for high-gain, low-noise preamplifier and small-signal amplification stages, it features a high current gain ($h_{FE}$) and an exceptionally low noise figure. It is ideal for audio preamplifiers, signal processing circuits, low-power switching, and sensor input networks, frequently serving as the complementary NPN pair to the 9015 PNP transistor.
