It has a gain of 67 to 220 and a transition frequency of 120MHz at I\u003csub\u003eC\u003c\/sub\u003e=1mA and V\u003csub\u003eCE\u003c\/sub\u003e=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.\u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003ch3\u003e\u003cstrong\u003eSpecifications\u003c\/strong\u003e\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eCollector-Base Volt (Vcbo): 30V\u003c\/li\u003e\n\u003cli\u003ehfe: 67-220 @ 1mA\u003c\/li\u003e\n\u003cli\u003ePower Dissipation (Ptot): 300mW\u003c\/li\u003e\n\u003cli\u003eCollector-Emitter Volt (Vceo): 20V\u003c\/li\u003e\n\u003cli\u003eCollector Current (Ic): 0.03A\u003c\/li\u003e\n\u003cli\u003eCurrent-Gain-Bandwidth (ftotal): 120MHz\u003c\/li\u003e\n\u003cli\u003eType: PNP\u003c\/li\u003e\n\u003cli\u003ePackage Type: TO-92\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e \u003c\/p\u003e\u003ch3\u003e\u003cstrong\u003eProduct Description\u003c\/strong\u003e\u003c\/h3\u003e\u003cdiv style=\"text-align: left;\"\u003e\u003cimg style=\"margin-bottom: 16px; float: none;\" alt=\"BF494 Transistor Pinout\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0300\/6424\/6919\/files\/BF494-NPN-Medium-Frequency-Transistor_480x480.png?v=1590832417\"\u003e\u003c\/div\u003e\u003cp\u003e \u003c\/p\u003e\u003cp\u003eAs it is an NPN transistor like \u003cspan\u003e\u003c\/span\u003e, \u003cspan\u003e\u003c\/span\u003e that means you have to provide base pin some voltage to get it in conducting\/saturation region.
