Thanks, somewhere i definetely have a Babani book on 555 timers....it clearly says that El caps cannot be used for timing in 555 circuits, as they tend to have too high voltage ratings, and dont work as caps.
Also, an extremely experienced Electronics manager told me that el caps dont form below 10% of rated voltage.
El caps have a similarity to batteries, and this is the origins of this.
.......***Quoting***.....
...quoting page 11 of the book "IC555 projects" by E.A.Parr (babani publishers) "An electrolytic capacitor does not become a capacitor until about 0.1 of its voltage rating....."
book first published in 1978
book revised and reprinted n 1981
Book printed last in 2006.
The permissible voltage range for continuous operation lies between the rated voltage and 0 V.
...thanks, but i believe that just means that its "permissible"...ie not going to damage the cap...but it wont have any capacitance below 10% of rated v,
