What is a capacitor?

A capacitor is a device that can store charge. The particular way it does this gives rise to several types of capacitors.

What is a ceramic capacitor?

Ceramic capacitors are made of many very thin layers of alternating metal and dielectric stacked together. If a ceramic capacitor has N plates then it has a total volume V of... Each dielectric will have a different Er value. For example, X7R may have Er of 3300 but may drift 15% over temperature.

What are the different types of capacitors?

Our range includes over 60,000 different capacitors including aluminium, tantalum, polymer, polyester film and ceramic capacitors. We source from globally renowned manufacturers AVX, Murata, KEMET, Panasonic, TDK and many more, so that you can rely on performance. What is a capacitor and what does it do?

Why are rated capacitors smaller than 20 years ago?

Know your capacitors. add specific capacitors ,,,like values or manufacturer part numbers...lot of factors varies.. Age. Similarly rated caps are much smaller now than they were 20 years ago. Probably caused by other reasons listed here. I can guess that the main difference is in cost.

Why should I buy a bigger capacitor?

Also, bigger capacitors will usually have higher voltage rating, they cool down better. It also might be age (caps get smaller with years) or manufacturing capabilities. For example of the latter: if you were to buy strictly "Made in Russia" parts, you'd have to tolerate with much larger packages for the same thing, say, Murata makes.

How do you identify a small ceramic capacitor with 2 digits?

2 digits and nothing else = pF. xNy = x.y nF. The small ceramic capacitors with 2 digits markings can be identified with their color and the type of markings: Generalizing, The small brown capacitors have written with the value of the capacitance with a multiplier 10^ (-12) i.e. picofarad
