BF494 NPN Medium Frequency Transistor

The BF494 NPN Medium Frequency Transistor is an NPN Medium Frequency transistor which can be used in low voltage low current applications. It has a gain of 67 to 220 and a transition frequency of 120MHz at IC=1mA and VCE=10V. It can be used in applications such as radio and television receivers, FM tuners, Low noise AM, mixer-oscillators, IF amplifiers in AM/FM receivers. The maximum collector current is 30mA so make sure you do not cross it and fry your transistor. SpecificationsCollector-Base Volt (Vcbo): 30Vhfe: 67-220 @ 1mAPower Dissipation (Ptot): 300mWCollector-Emitter Volt (Vceo): 20VCollector Current (Ic): 0.03ACurrent-Gain-Bandwidth (ftotal): 120MHzType: PNPPackage Type: TO-92 Product Description As it is an NPN transistor like BC547, 2N2222 that means you have to provide base pin some voltage to get it in conducting/saturation region. Care should be taken to keep the currents under maximum permissible limits as its maximum power dissipation is 300mW.
