Le transistor utilisé présente un gain de 200, le courant de base Ib devra être d'au moins 0,1 A / 200, soit 0,5 mA. Amplifier circuits use a transistor and direct current (DC) voltage to increase the power level of an input alternative current (AC) signal. If you continue to use this site we will assume that you are happy with it. All Rights Reserved. It comes in a TO-92 package, this transistor can drive max load around 150mA that is enough to operate many devices in a circuit for LEDs, Relays, ICs, transistors and other parts of electronics circuits. Most of the ones I have seen have been small radio component sized devices. Many of these transistors contain three discrete leads that go to the transistor’s semiconductor regions. Discover (and save!) Home Low Power Amplifier Circuit Transistor Amplifier Simple Amplifier with C945 ,MJE340, and TIP3055. It requires a preamp in the function of it hasn't got much advance. For an amplifier that is based on an NPN transistor, the AC signal is passed through the base region on the transistor. Shenzhen Jiexing Weiye Electronic Co., Ltd.

Both the types NPN and PNP transistors can be operated as switches. IC - LM555 x1 (2.) Circuits such as a small-signal amplifier or a high-speed switching circuit might employ one or more C945 transistors. About 18% of these are transistors, 14% are integrated circuits, and 1% are other electronic components. A voltage differential between the collector and emitter regions on the transistor add power to the AC signal, and the output AC signal is obtained by connecting the output device to the collector region on the transistor. Required fields are marked *. Your email address will not be published. Simple Amplifier with C945,MJE340, and TIP3055 Editor Electronic Circuit Published Monday, April 16, 2012 This simple amplifier does sound good quality Power output about 10 - 14 Watts with Supply voltage about 34 - 36 Volt DC. Onetouch 1688.com Intellectual Property Protection There was a time when it seemed manufacturers were determined to cram as many components on as small a PCB board as possible. Products Information : About Ship Way : we can use :DHL,FEDEX.TNT.UPS.EMS. This configuration allows the C945 transistor to conduct electric current between the collector and emitter regions when voltage is applied to the transistor’s base region. Subscribe to the latest articles from this blog directly via email. An NPN bipolar junction transistor — such as the C945 — contains a base region that is doped with positive, or P-type, semiconductor material, along with collector and emitter regions that are doped with negative, or N-type, semiconductor material. I would assume the bigger the transistor the larger the power needed to make it function properly. C945 Datasheet (PDF) 0.1. It is manufactured in TO-93 package, the max load this transistor can drive is around 150mA or 0.15A that is enough to operate many devices in a circuit for example LEDs, Relays, ICs, transistors and other parts of a circuit. This simple amplifier does sound good quality Power output about 10 - 14 Watts with Supply voltage about 34 - 36 Volt DC. 2pc945 3.pdf Size:47K _philips DISCRETE SEMICONDUCTORS DATA SHEET ndbook, halfpage M3D186 2PC945 NPN general purpose transistor 1999 May 28 Product specification Supersedes data of 1997 Mar 26 Philips Semiconductors Product specification NPN general purpose transistor 2PC945 FEATURES PINNING • Low current (max. Circuits such as a small-signal amplifier or a high-speed switching circuit might employ one or more C945 transistors. During this condition, there might be no requirement of using another signal transistor to drive this transistor. A C145 transistor is best used in low-power applications. A typical relay might take five milliseconds to engage and 10 milliseconds to disengage, but a C145 transistor can switch on or off 150 million times per second. We can ship out within 1-3days after you confirmed the payment.
