Why do capacitors use tolerance codes?

Capacitors use tolerance codes, much like resistors, standardized by the Electronic Industry Alliance (EIA). These codes indicate how much the actual capacitance may deviate from the marked value. This precision is ideal for designing and maintaining high-accuracy circuits.

What is a capacitor marking?

Capacitor markings are used for identifying their values and proper usage in electronic circuits. Here's a detailed breakdown of the key aspects to consider: On smaller capacitors, you often find only the capacitance value. For larger capacitors, two main parameters are displayed: capacitance and breakdown voltage.

What is a series capacitor?

The series capacitor units and banks are usually intended for high-voltage power systems. This standard is applicable to the complete voltage range. This standard does not apply to capacitors of the self-healing metallized dielectric type. The following capacitors, even if connected in series with a circuit, are excluded from this standard:

What is a 100 F capacitor tolerance?

For instance, if a capacitor is marked as 100 μF with a tolerance of ±10%, it means the actual capacitance can be between 90 μF (100 - 10%) and 110 μF (100 + 10%). This range must be considered during design to ensure circuit performance is not adversely affected. 4. Can I Use a Capacitor with a Higher Tolerance?

What does a color code on a capacitor mean?

While most modern capacitors use numerical markings, older models often display color codes. These codes indicate values like capacitance and breakdown voltage through a series of colored bands. Figure 2: Standard Capacitor Color Code Each color band on a capacitor represents a specific number or multiplier.

How do you know if a capacitor is 2a474j?

If a capacitor is f.ex. marked 2A474J, the capacitance is decoded as described above, the two first signs is the voltage rating and can be decoded from table 2 here below. 2A is 100VDC rating according to the EIA standard. Some capacitors are only marked 0.1 or 0.01, mostly in these cases the values are given in uF.
