Unbiased coupling is a serious problem in circuits.
(No. 1) - Black Gate capacitor applications:
Operational amplifiers (op-amps) are easy and convenient to use, and they are very often employed in analog and digital circuits. These amplifiers use bi-polar power sources and they have unbiased input and terminals. However, this requires the use of coupling capacitors to remove the polarization caused by normal, polarized electrolytic capacitors. Sometimes non-polarized capacitors are used end in other cases polarized capacitors are hooked up backwards, or in series, to try and deal with the problems. These methods of controlling op-amps inevitably create significant problems with the signals being processed.
Electrolytic capacitors are at their worst in unbiased operation under the following conditions:
BG-Ns (non-polarized Black Gate capacitors) do not contribute to these types of distortion. On the contrary, they other the best performance among the Black Gate series. The internal construction of BG-Ns Is absolutely and completely symmetrical and they function essentially the same as an electron transfer. They are almost ideal capacitor with the following advantages:
Therefore, when used for zero-bias coupling, they provide the very best results. The number of applications for BG-Ns is huge. in audio devices: preliminary amplifiers, main amplifiers, microphones, compact disk players, and professional mixing consoles can all benefit. in video devices: TV monitors, video tape recorders, and TV cameras will show improved pictures. in office automation equipment, modems are greatly enhanced. in medical equipment: EKGs, EEGs, and CGs provide cleaner, more accurate readings.
Our brand-new BG-N50V/1µ and BG-N50V/4.7µ can be used to improve the input and output Impedance of all kinds of electronic equipment. Why don't you try these new, non-polarized Black Gates in your application?
