A capacitor with lowest leakage is Paper or Ceramic or Polyester or Mica?
mica
Can a capacitor in a lcd television be changed if cant find exact numbers eg 220 25v instead of 220 16v and what would change be?
Yes, the higher voltage is not only OK, but is desirable, as it will be longer-lasting. It is very important to replace the capacitor with the same type. If it is a ceramic disk, replace it with a ceramic disc. If it is metal-film, then replace it with a metal-film capacitor, and so on.
What is the use or ceramic capacitor?
ceramic capacitor does not simultaneously discharges instead it maintains stead flow of charges through it
Can you replace 47n polyester capacitor with a 47n polarised?
Last time I looked there are no 47nF polarized capacitors. The value is too small to make practically.
What does polyester capacitor do in a circuit?
same as any other capacitor. however they are usually used where higher voltages are.
What is an unpolarized capacitor?
A capacitor that does not have a designated + and - side. Electrolytic capacitors are usually polarized. Ceramic capacitors are not.
What is a mkt capacitor?
It is a type of capacitor, with a shell of metallized plastic polyester.MKT is a german acronym for:metallisierter kunststoff polyester
How do capacitors classified?
capacitors are classified on the basis of dielectric material used inside it. For example the electrolytic capacitor consist electrolyte as dielectric mica capacitor consist mica as dielectric between plates and ceramic capacitor consist ceramic as dielectric.
What is the response of ceramic capacitor in MHz and GHz Range frequencies?
That depends on the value of the capacitor and other components in the circuit.
When might it be necessary to use a 2 µF polyester capacitor rather than a 2 µF electrolytic capacitor?
when high voltages are present because the voltage rating of polyester (polyethylene terephthalate) capacitor is high as well as electrolytic capacitor will destroy if the voltage increases from nominal voltage and cause short circuit conditions.
What is use of decoupling capacitor?
to protect a circuit from damaging
Why it is necessary to connect ceramic disc capacitor across filter capacitor?
The filter capacitor has inductance and is therefore not very responsive to short term transients, i.e. fast rising or falling current edges. The ceramic disk capacitor, on the other hand, has very little inductance, and therefore is very responsive to short term transients. It is normal "best practices" to connect a small ceramic disk capacitor at each IC's Vcc terminal while also using bulk capacitance in the power supply and at various other places. For the same reason, you want a ceramic disc at the main filter capacitor in the power supply.
