What Does 104 Mean on a Capacitor?
Understanding Capacitor Markings
Capacitors are electronic components that store electrical energy. They are commonly used in various electronic circuits, such as power supplies, filters, and timing circuits. To identify the value and other characteristics of a capacitor, manufacturers use a system of markings printed on the capacitor’s body.
104 on a Capacitor
The marking “104” on a capacitor indicates the following:
- Value: 100,000 picofarads (pF)
- Tolerance: ±5%
Value (100,000 pF)
The first two digits (10) represent the significant digits of the capacitance value, and the third digit (4) indicates the multiplier. In this case, 4 represents 104, resulting in a capacitance value of 100,000 pF.
Tolerance (±5%)
The letter “F” following the capacitance value represents the tolerance, which indicates the allowable deviation from the nominal capacitance value. A tolerance of ±5% means that the actual capacitance value can vary by up to 5% above or below the nominal value (100,000 pF). In this case, the actual capacitance can range from 95,000 pF to 105,000 pF.
Applications of 104 Capacitors
Capacitors with a value of 100,000 pF are commonly used in various applications, including:
- Timing circuits
- Frequency filters
- Smoothing circuits
- Energy storage
Conclusion
Understanding the marking “104” on a capacitor is essential for correctly identifying its capacitance value and tolerance. This information is crucial for selecting the appropriate capacitor for electronic circuits and ensuring proper circuit operation.
