In this video, electrical engineer Barron Stone demonstrates how to determine the capacitance value of a ceramic capacitor by decoding the common three digit codes. Learn the different letters that are used to indicate the capacitor's tolerance.
- [Instructor] It's really easy…to determine the value of electrolytic capacitors…which are the cylindrical capacitors…that look like tiny tin cans.…The capacitance value and maximum voltage…that an electrolytic capacitor can withstand…is usually printed on the side…in large easy-to-read letters.…For example, the capacitor shown here…has a capacitance value of 1,000 microfarads…and it can withstand up to 25 volts.…Additionally, since electrolytic capacitors are polarized,…you'll see one side clearly marked with a minus symbol…to indicate that it's the negative cathode side.…
Identifying the capacitance value of ceramic capacitors…is a bit trickier than with electrolytic capacitors.…Ceramic capacitors are too small…to print a lot of information on…so most manufacturers use compact codes…of letters and numbers to indicate the capacitance value.…One of the most commonly used standard of codes…for capacitor values uses three numbers…to express the value of the capacitor…in terms of picofarads.…It works in a similar way…
