Q: What are capacitor code values? A: Capacitor code values are used to represent the capacitance value of a capacitor component. Capacitors are electronic components that store and release electrical energy. The code values help in identifying the capacitance value of a capacitor without having to write the full value in Farads. The material used in an aluminum electrolytic capacitor is aluminum oxide-coated paper with an electrolyte of Aluminium sulfate and distilled water. The electrolyte is impregnated into the paper, and the paper is coated with aluminum (aluminum oxide) by thermal decomposition of aluminum. The aluminum formed thereby is the dielectric film. Some small capacitance capacitors can be marked with an R between numbers. If the code is 3R9 then R is an indicator of values Less than 10pF and has nothing to do with resistance. 3R9 would be 3.9pF capacitor voltage code table Modern capacitors use the numerical markings we outlined above, but older capacitors employed a (now obsolete) color coding system. 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. Other Capacitor Values Finally, the leads are connected by soldering or wire-bonding to complete the electrical connections and to protect them from corrosion. Ceramic disk capacitors are manufactured in different shapes such as round, rectangular, cylindrical, and metalized chips. What is Ceramic Capacitor 104?

Usually, ceramic capacitors are constructed by depositing a ceramic or metal film on a ceramic or metal substrate. The depositing of the film is generally done using a printing process, which is most commonly an electrostatic printing process. Q: How do I interpret a three-digit capacitor code value? A: In a three-digit capacitor code, the first two digits represent the significant figures, and the third digit represents the multiplier. To determine the capacitance, combine the first two digits and multiply them by 10 raised to the power of the third digit. For example, a code of “104” translates to 10 x 10 Ceramic capacitor 104 is a type of non-polarized capacitor that can be used to store and filter electric charges. It has a wide range of capacitance and voltage and it has a negative temperature coefficient. Ceramic Capacitor 104 Applications Every capacitor usually has two numbers that characterize it. These are its capacitance and voltage rating. The latter tells us the maximum voltage at which the element will still work correctly. The producers often write the capacity directly, so when you see a capacitor with 220 µF 25 V, it simply means that it has a capacity of 220 µF and works safely with voltages up to 25 V. The conductor is formed by screen printing, which consists of applying a paste (the conductive element) onto the ceramic carrier and firing at a high temperature (around 800 degrees Celsius).

Note that tiny capacitors – under 1000μF – will indicate the capacitance directly in picofarads. You may see a number between 1 and 999 written directly on them. It’s important to know the general range of capacitance to understand how to read the numbers. You’ll need to know the difference between 134μF written directly or at 130,000μF written in an exponential coding. If a capacitor is marked with 2A474J, the capacitance is decoded as described above, the two first signs is the voltage rating and can be decoded from the table given below here. 2A is a 100VDC rating according to the EIA (Electronic Industries Alliance) standard. When Any capacitor has 104 printed- It has a multiplier of 4 (Third number of code ). 10 is multiplied by 10×10 4 =10000. Then its value is 10×10000= 100000PF Capacitor code table/chart The 100uf, 50v ceramic capacitor has a working voltage of 50 volts. It also has a tolerance range of ±20%, which means that the values may be anywhere between 40 and 60 v or between 80 and 120uf. Ceramic Capacitor 104 is a ceramic capacitor with values ​​ranging from 1 pF to 220,000 F. Its maximum voltage is 50 V and its minimum voltage is 16 V. It has a negative temperature coefficient which means that as the temperature increases, its capacitance will decrease with a rate of 0.005%/cCelsius degree rise

To find the last digit, we have to use proper capacity units, pF – 1.2 µF = 1,200,000 pF = 12 × 10⁵ pF.Sometimes a manufacturer will not adhere to the EIA coding system, and mark the values directly on the capacitor. Here are some examples of such marking. High voltage capacitors are sometimes referred to as power capacitors. Like other high voltage capacitors, they are designed to withstand high voltages for short durations. They are used in applications where the capacitors are charged and discharged (or sometimes discharged only) at high voltages. Conclusion
