Difference between ceramic and electrolytic capacitors?
In ceramic capacitors the dielectric is a thin layer of ceramic and both plates are metal foil. These capacitors are unpolarized. These capacitors have negligible internal inductance or resistance.In electrolytic capacitors the dielectric is an ultra thin layer of corrosion on the surface of a metal foil plate and the other plate is an electrolyte paste. These capacitors are polarized and if connected backwards are likely to explode. These capacitors have significant internal inductance, making them bad filters of noise in the MHz range and above which requires ceramic capacitors.
What is the functions of ceramic capacitor?
Ceramic capacitors can be used anywhere a capacitor having very low internal parasitic inductance is required. Most commonly they are used as powersupply bypass capacitors. They are also sometimes used for coupling capacitors for HF signal amplifiers.
Is capacitor polarity sensitive?
Some capacitors are polarity sensitive; some are not. It depends on the design. Electrolytic capacitors, for instance, are polarity sensitive, while ceramic disc capacitors are not. You can generally tell, if the capacitor is marked with polarity signs, such as + and -, if it is or not.
How ceramic capacitors can do filtering in replacement of electrolytic capacitors?
Electrolytic capacitors do a very good job of bulk filtering, but they have poor high frequency performance due to distributed inductance. The ceramic capacitor has excellent high frequence response, and will often be used in parallel to the electrolytic to filter out fast rise time step changes in current demand.
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 are the different types of capacitors?
Ceramic capacitors, film capacitors, multi-layers ceramic capacitors, electrolytic capacitors, mica capacitors, super capacitors, etc. -- We're JYH HSU(JEC) Electronics Ltd (or Dongguan Zhixu Electronic Co., Ltd.), an electronic components manufacturer.

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.

Can you replace ceramic capacitor with a polyester?
yes ceramic can be replaced by polyester

What type of capacitor is normally polarized?
There are many different cpacitor technologies, or 'types'. To name a few, there are Electrolytic, Ceramic, Polypropylene Film, and Metalled Paper capacitors. The only type of capacitor commonly polarized are Electrolytic Capacitors. This means DC supply only. Dealing with AC? I'd recommend ceramic.
What is schematic symbol of the paper capacitor?
paper capacitors are non polar, so they have the same symbol as any other non polar capacitors like ceramic disc, two parallel lines.

How do you read the value of a ceramic capacitor?
Most ceramic capacitors use a numbering scheme similar to the resistor color code. Usually, three numbers are given.The first two numbers are significant figures, and the third is the base 10 multiplier, or number of zeroes to add onto the end.With ceramic capacitors, the value you get is typically assumed to be in picofarads (pF, 10-12 Farads). For much larger capacitors, the value is sometimes given in micro-Farads (uF, 10-6 Farads).For example, for a capacitor marked "154":1: First sig. fig5: Second sig. fig4: multiply by 104 (add 4 zeroes)Result: 150,000 pFNow, you can divide by one million to get an answer in uF, if that is more comfortable for you to work with:150,000 pF = 0.15 uFTherefore, a capacitor marked 154 has a value of 0.15 uF.This should get you started reading ceramic capacitor values. For more detail, see the "coding" section of the wikipedia article on ceramic capacitors.
