Let us see an example of ceramic or disc capacitor for calculating the color code on it. Disc & Ceramic Capacitor. Disc capacitors with colour codes. These colour codes are used from many years for non-polarized capacitors like disc and ceramic capacitors. But it is difficult to identify the values in the case of old capacitors. In case of Color coded capacitors, capacitor body consists of color bands and by using a capacitor color code chart we can easily identify the capacitor value. The first color is considered as the 1 st digit in color chart, the second color band is 2 nd digit, the third band is a multiplier, the 4 th band is tolerance and the fifth color band.

Ceramic, tantalum, electrolytic capacitors are few of the available options when it comes to SMD capacitor. ceramic capacitors are easy and cost-effective to manufacture and thus most widely used.

This calculator converts capacitance value between units pF, nF, µF and F. The capacitor code conversion chart lets you find the capacitance by looking up the code. The first two digits are the value in picofarads, while the third is the multiplier. If no multiplier is given the result is capacitance in pF.

What is an SMD capacitor?

SMD capacitor is nothing but a capacitor with compact size and no long lead. It is developed in such a way that it offers an advantage for mass production of electronic devices and equipment, along with some technical advantage in the operation of high-frequency devices.

Advantage of SMD capacitor:

SMD capacitor has no leads or very short lead, the inductive effect of leads are avoided ( its importance comes into the picture when we are working on high-frequency circuits and radio circuits ‘RF range’).
Eg. while designing a tank circuit using LC, if the leads of the capacitor are not kept short then it will oscillate at different frequencies than that we have designed.
The size of the surface mount capacitor is smaller than the traditional capacitor space and the device can be confined in a smaller area, useful in portable devices.
An increase in the manufacturing speed, therefore, reduction in cost is possible.
Due to the standard size, it is much easier to handle and place on PCB using the robotic assembly process.

Disadvantage of SMD capacitor:

Its advantages have an upper hand than that of disadvantages. Why we are saying its disadvantages are very few and can be neglected.

One disadvantage is its size when it comes to repairing. Suppose you’re considering to replace it then it is a little bit arduous work.
Lower heat capacity of a smaller capacitor can damage it if proper cooling ventilation is not given. Surface mount components lower operating temperatures than the traditional one.

Common capacitor value with codes in a chart:

Common capacitor value for SMD capacitor is almost same as ceramic and electrolytic capacitors. Below table have all the common capacitor values listed that are useful for you.

For code “104″
The two figures 10 indicate the significant figures and the 4 indicates the multiplier , i.e. 10^4 = 10000.
Therefore, the value comes out to be 100000 pf = 0.1 uf

Are SMD capacitor polarized?

YES, SMD capacitors are polarized but not all SMD capacitors are polarized. The electrolytic SMD capacitor compulsorily comes with the polarity and has its dedicated applications.
They are normally yellow and black color with markings on it.

How to identify SMD capacitor polarity?

The polarity of surface mount capacitors is marked by a white or black line at one of the ends of the device. Note that on a rounded surface mount capacitor the small black corner indicates the negat
