Capacitor value chart

The three-digit capacitance code works as follows:

<ol class="X5LH0c"><li class="TrT0Xe">If the third digit is 0 through 6, add that many zeroes to the end of the number. (For example, 453 → 45 x 10<sup>3</sup> → 45,000.)</li><li class="TrT0Xe">If the third digit is 8, multiply by 0.01. (e.g. 278 → 27 x 0.01 → 0.27)</li><li class="TrT0Xe">If the third digit is 9, multiply by 0.1. (e.g. 309 → 30 x 0.1 → 3.0)</li></ol>

What are the values of capacitors?

The nominal value of the Capacitance, C of a capacitor is the most important of all capacitor characteristics. This value measured in pico-Farads (pF), nano-Farads (nF) or micro-Farads (μF) and is marked onto the body of the capacitor as numbers, letters or coloured bands.

What value is a 104k capacitor?

So the capacitance value for 104 will be 100000 picofarads or 100 nanofarads or 0.1 microfarad.

What is the value of 100 capacitor?

Picofarad (pF)	Nanofarad (nF)	Code
100	0.1	101
120	0.12	121
130	0.13	131
150	0.15	151

What numbers matter on a capacitor?

The higher the voltage rating on your capacitor (or other electrical item) the faster the electrical current moves. The second rating is the microfarad (MFD) rating. A microfarad is a term to describe a capacitor's level of capacity. That means the higher the microfarad rating, the more electrical current it can store.

What does 10 uF mean on a capacitor?

A ten micro-Farad capacitor is written as 10µF or 10uF. A one-hundred nano-Farad capacitor is written as 100nF or just 100n. It may be marked as 0.1 (meaning 0.1uF which is 100nF).

How do you size a capacitor?

Multiply 0.5 times the square of the voltage. Call this result "x.". Continuing the example, you have 0.5 times 11.5 volts times 11.5 volts, or 66.1 square volts for "x". Divide the start-up energy requirement, in joules, of the motor by "x" to arrive at the capacitor size needed in farads.

Can I use a 440v capacitor instead of a 250v?

A: no, it can't, this component have to be replace for a capacitor of 450v value or more, and the capacitance have to be the same value.

What are 0.1 UF capacitors for?

This is a 0.1uF - (104) Ceramic Capacitor Use this capacitor for power decoupling, having a smooth power in your circuit, timing circuits etc. It is always a good idea to put one of these next to the power pins of a microcontroller.

What is 105J 400V capacitor?

1uF/400V (1000nF -105J) – Polyester Film Capacitor (originally known as a condenser) is a passive two-terminal electrical component used to store energy electrostatically in an electric field.

What does 102 mean on a capacitor?

9. 0,1. For example: A capacitor with the number 102 printed on it means a 10 with two zeros. The value in this case is 1.000 pF or 0,001 µF also named 1 nf. More examples below.

What does 103 mean on a capacitor?

The example capacitor has a 3 digit number printed on it (103). The first two digits, in this case the 10 give us the first part of the value. The third digit indicates the number of extra zeros, in this case 3 extra zeros. So the value is 10 with 3 extra zeros, or 10,000.

What is standard capacitor?

[′stan·dərd kə′pas·əd·ər] (electricity) A capacitor constructed in such a manner that its capacitance value is not likely to vary with temperature and is known to a high degree of accuracy. Also known as capacitance standard.

How do you calculate capacitance value?

This calculates the capacitance of a capacitor based on its charge, Q, and its voltage, V, according to the formula, C=Q/V.

What does 473 mean on a capacitor?

This is a 0.047uF - (473) Ceramic Capacitor Use this capacitor for power decoupling, having a smooth power in your circuit, timing circuits etc.

What happens if you put a bigger capacitor?

This is not to imply bigger is better, because a capacitor that is too large can cause energy consumption to rise. In both instances, be it too large or too small, the life of the motor will be shortened due to overheated motor windings.

Is it OK to replace a capacitor with a high MicroFarad value?

You can almost always replace a capacitor with one of a higher voltage. This is the limiting factor of a capacitor due to dielectric breakdown voltages that the manufacturer chose. Varying capacitance gets a little trickier.

What happens if we increase the capacitor value?

As the capacitor value increases, the motor draws less current. The main winding current decreases with any increase in capacitor value or in the motor speed.

Can I replace a 250v capacitor with a 450v?

In both instances, be it too large or too small, the life of the motor will be shortened due to overheated motor windings. Can you replace a 250v capacitor with a 450v? no, it can't, this component has to be replaced for a capacitor of 450v value or more, and the capacitance has to be the same value.

Can I replace a capacitor with a higher voltage?

Replacing a capacitor with something that has a higher voltage rating is always safe. The only problem there is that a capacitor rated for a higher voltage is often physically larger, everything else being equal.
