jb Why You Use Capacitor in Transistor Amplifier Circuit?

Keywords: Ripple Voltage, AC power supplies, audio amplifier, open-loop

Capacitors are used to couple each stage of an amplifier to the next, to help remove ripple voltages from rectified AC power supplies and they are also used to tune circuits to get the required frequency response, such as a tone control in an audio amplifier, or an RF or IF amplifier in a radio receiver front-end.

Capacitors are also used to bypass emitter resistors to improve the voltage swing and lower the AC output impedance of class A amplifier stages, and also used in negative feedback loops to stabilize an amplifier's open-loop gain.

We jb capacitors company professional produce MKT & MKP film capacitors, total 22 series. we have two representitive types used in Amplifier, audio, sound system. please check below.

jb X2 Film Capacitors Lastest News

Arcotronics Kemet, Epcos,Pilkor, EVOX RIFA, Panasonic lead time is very very long, one customer told me this morning Arcotronics Kemet R46 X2 need 371days, that is 53 weeks, over 1 year....

But JB X2 lead time is only 5-7 weeks, for common value like 0.1uF even can meet 4-5 weeks.

Jb Capacitors produce MKT, MKP, X2 film capacitors and electrolytic capacitors. We have cross for above mentioned brands, we produce and sell under jb capacitors brand.
