Description
Designed especially for low cost, high reliability type
applications, this NPN Silicon Planar Transistor offers
low noise, high gain performance, which meets or
exceeds all JAN specifications. These devices can be
fully tested and screened in accordance with MIL-MRF-
19500 procedures. A 1.8 GHz current gain-bandwidth
product (f_T) is typical for this device. The transistors are
rugged and employ gold metalization for an
unprecedented reliability.
Applications
IF, VHF, UHF, TV and RF amplifiers.
Case Style TO-72 CAN (509)
