looking for Polyster Caps in pico farads

[haseeb]

Hi Diyers,

I am looking for polyster caps in pico,nano,micro farad values.

Will these be available in india ? if yes, where can I get the catalog any site information is appreciated.

Thanks

Polyester caps generally go down to about .0001µf (100pf). From there and up, you should have no problem finding them (up to a maximum of about 10µf, unless you want to look at large speaker crossover-type poly caps which can be had up to values of about 200µf).

Thanks very much echowars.

I was in confusion about the convertions pf to uf and the range of availablility especially range of availablity.

I found a an url where all convertions are avialable. http://www.unitconversion.org/unit_c...pacitance.html

In india, I don't think we can get 200 uf poly caps ,any way I am looking for pf's upto 1000pf.

Can u clarify another point ?, when i asked for 0.1uf poly cap the store keeper gave me a polyster cap rating as 104k,104j what is this convertion ? any idea ?.

[cliffforrest]

104 = 10+ 4 zeroes, ie 100000 or 100,000

Units are pF so 100,000pF = 100nF = 0.1uF, which is what you asked for

suffix k and j are tolerence, 10% and 5%

Do you think you could use mica caps instead of polyester? Mica is more common in the picofarad region than is polyester.

I like polyster caps than mica.
