HOW TO READ CERAMIC CAPACITOR VALUES HOW TO

If you come across these capacitors, try looking up a capacitor color code guide like the one here to decipher the codes for capacitance, breakdown voltage, and other values. Modern capacitors use the numerical markings we outlined above, but older capacitors employed a (now obsolete) color coding system. Also note the indications for the breakdown voltage and operating temperature. Usually the line is white, but below you can see a capacitor with a black stripe marking the negative pole. If the capacitor bears a second value, it will typically be its breakdown voltage, expressed as a number followed by V, such as РІР‚Сљ25VРІР‚Сњ or РІР‚Сљ100V.РІР‚СњР”Р‡inally, in the case of a capacitor with polarized leads, youРІР‚в„ўll typically see a colored stripe on the negative side. YouРІР‚в„ўll need to know the difference between 134РћСF written directly or at 130,000РћСF written in an exponential coding.Р”Р„fter capacitance, the next most important spec is the breakdown voltage.

ItРІР‚в„ўs important to know the general range of capacitance to understand how to read the numbers. You may see a number between 1 and 999 written directly on them.

Note that tiny capacitors РІР‚вЂњ under 1000РћСF РІР‚вЂњ will indicate the capacitance directly in picofarads. The numbers eight and nine refer not to an exponential power of eight and nine, but to a multiplier of.In this marking formula, it is important to note that the final digit may indicate a few different things:
