What do the numbers on my capacitor mean?

If you have a capacitor that has nothing other than a three-digit number printed on it, the third digit represents the number of zeros to add to the end of the first two digits. The resulting number is the capacitance in pF. For example, 101 represents 100 pF: the digits 10 followed by one additional zero.

What does Z mean on a capacitor?

Posted by ejeffrey on 11 Jul, 2011 19:22. Yes. That is a common tolerance rating on capacitors intended for power supply filtering, including a lot of aluminum electrolytics. The tolerance doesn’t matter much, and especially extra capacitance almost never hurts.

What can I do with a capacitor?

A capacitor can store electric energy when it is connected to its charging circuit. And when it is disconnected from its charging circuit, it can dissipate that stored energy, so it can be used like a temporary battery.

How big is the 2kV 471k ceramic capacitor?

2kv 471k Exported To Worldwide High Voltage Ceramic Capacitor is a small capacitor with 6.3mm diameter. Capacitance tol.: Q: How long is the mass production time?

What is the value of a ceramic capacitor?

Sometimes, there’s also a value expressed in pF or µF, and you have to guess which is right. Some examples: A ceramic capacitor with the number “470” on it likely has 470 pF, because ceramic caps are still mostly used for small-ish values.

Which is smallest C0G or X7R capacitor?

For example, if you go onto Digi-Key and search for a 0.1 µF C0G cap, the smallest in-stock part is a 1206. In contrast, you can find a 0.1 µF X7R cap in the 0306 package, and with a voltage rating (10 V) high enough for 3.3 V or even 5 V circuitry.

What’s the difference between X5R and y7v capacitor?

X5R and X7R are in Class 2, and Y5V is in Class 3. The first character indicates the lowest temperature that the capacitor can handle. The second character indicates the maximum temperature. The third character indicates the maximum amount of capacitance change over the part’s temperature range.
