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 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.

We can also ask the reverse: What is the capacitor code for a known capacity? Let's try with a capacitor with C = 1.24 µF: To find the last digit, we have to use proper capacity units, pF – 1.2 µF = 1,200,000 pF = 12 × 10⁵ pF. 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. 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 In this marking formula, it is important to note that the final digit may indicate a few different things:Therefore, a disk capacitor could be constructed that was smaller than electrolytic capacitors of similar capacitance. This was very attractive for applications requiring a very small capacitor. Ceramic disc capacitor markings 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. 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 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? 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.

You can only compare up to four products at a time.

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 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. 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. 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 The first two numbers describe the value of the capacitor and the third number is the number of zeros in the multiplier.
