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 We need two digits for the initial two digits of the code, so it's time to round the value to two significant figures - 1.24 µF → 1.2 µF. So the code will start with 12·. 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. 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. The numbers eight and nine refer not to an exponential power of eight and nine, but to a multiplier of .01 (x 10 -2) and .1 (x 10 -1) respectively
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. ConclusionTo find the last digit, we have to use proper capacity units, pF – 1.2 µF = 1,200,000 pF = 12 × 10⁵ pF. High voltage ceramic capacitors are typically used in circuit designs to withstand high voltages for a short duration. Capacitance values range from 0.1 pF to 10,000 pF and inductances from 1 to 10 µH.
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.

When the first two numbers are multiplied with the multiplier, the resulting value is the value of the capacitor in picofarads. 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 Ceramic Disc Capacitor 104 is a type of capacitor used in electronic devices to regulate voltage or power. Ceramic capacitors are constructed from a thin disk of ceramic material, which has a large surface area and a high dielectric constant.
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 After capacitance, the next most important spec is the breakdown voltage. If the capacitor bears a second value, it will typically be its breakdown voltage, expressed as a number followed by V, such as “25V” or “100V.”Q: What is the most common type of capacitor code value? A: The most common type of capacitor code value is the three-digit code, which represents the capacitance in picofarads (pF). For example, a capacitor with the code “104” indicates a capacitance of 10,000 pF or 10 nF. In this marking formula, it is important to note that the final digit may indicate a few different things: 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? In addition to this, it can be used as a coupling capacitor since a 100uf ceramic capacitor provides isolation between the input and output circuits of a device. What is a 100 nf ceramic capacitor? 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.
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 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.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 nf ceramic capacitor is a type of aluminum electrolytic capacitor. It has the symbol “100n” or 100μF (microfarad). A 100 nf ceramic capacitor is manufactured to handle AC signals at frequencies of up to 500 kHz. The 100nF one is very important as it is the lowest unity-gain stable oscillator in an RC circuit. Component manufacturers indicate tolerance with a letter code that refers to variances as small as +/- 0.5pF (indicated as A) up to -20/+80% (written as Z). The capacitor tolerance chart below shows some common tolerance letter codes:
