3904 transistor3/26/2023 ![]() An important part of any telephonic device such as cell phones & smartphones.A must for sound cards in various electronic devices such as computers & laptops.Its continuous collector current will be 200mA, and the typical collector-Emitter Voltage is 40V. It is present in a To-92 Package and has a collector-Base Voltage of 60V. Also, features a maximum DC Current Gain (hFE) of 300. Used for electronic media production & recording applications such as live music & recording studio applications. It belongs to the class of Bi-Polar NPN transistors.Transistors Bi-Polar NPN Transistor 2N3904 Transistor. ![]() This circuit can easily be operated between 3V-9V DC. Buy online 2N3904 is an NPN transistor from hnhcart at lowest price for the collector and. Then the output audio signal is received from the collector terminal of the transistor & sent to an audio transducer (Loudspeaker) through the C2 capacitor (0.1μF), The gain of which can be tuned by connecting a 10KΩ pot. Transistors expect you to know what current you need to correctly define the case. Wholesale Online The Style of Your Life 5 pieces 5 x 2n3904-2n 3904 Transistor Si-M 60v 0.2a B 100-400 Free Shipping Worldwide, US 2. Remember as Mike Green said, the 2N3904 is a TO92 style transistor and you must put a resistor on the collector side to keep the current under 200mA or have a load equal to the resistor or it will get extremely hot and magic smoke will emerge. The 10KΩ resistor attached to the transistor through its collector allows the triggering of the AC component, while the 100KΩ resistor acts as a collector coupling resistor. 5 pieces 5 x 2n3904-2n 3904 Transistor Si-M 60v 0.2a B 100-400. NPN switching transistor MMBT3904 FEATURES Collector current capability IC 200 mA Collector-emitter voltage VCEO 40 V. Choose the appropriate base power supply VBB and collector power supply VCC, as well as Rb and Rc to ensure that the 2N3904 works in an amplified state. The base resistance Rb and the collector resistance Rc are used to convert voltage changes into current changes. The 0.1μF capacitor ( C1) stops the DC component of the transmission, allowing the AC input from the microphone to enter the transistor ( Q1) through its base. The transistor selects the transistor 2N3904. The 10KΩ resistor on the microphones +ve terminal provides the specific voltage level required for this procedure. The 2N3904 is a common NPN BJT used in the applications of general-purpose switching or low-power amplifying applications.
