how to read film capacitor?
Reading a film capacitor can be a bit tricky, but here’s a general guide:
Understanding the Code:
Film capacitors often use a code to indicate their capacitance and voltage rating. A common format is a three-digit code, where:
- First two digits: Significant figures of the capacitance value.
- Third digit: Number of zeros to add to the first two digits.
Example:
- 473:
- First two digits: 47
- Third digit: 3
- Capacitance: 47,000 picofarads (pF) or 0.047 microfarads (µF)
Voltage Rating:
The voltage rating is often printed directly on the capacitor, usually in volts (V). Sometimes, it might be indicated by a letter code. Refer to the manufacturer‘s datasheet for specific codes.
Additional Information:
- Tolerance: This indicates the allowable deviation from the specified capacitance value. It’s often expressed as a percentage, like ±10%.
- Temperature Range: This specifies the temperature range over which the capacitor can operate reliably.
- Dielectric Material: This indicates the type of plastic film used as the dielectric, such as polypropylene or polyester.
Tips for Reading Film Capacitors:
- Consult the Datasheet: If you’re unsure about the markings, refer to the manufacturer‘s datasheet for specific information.
- Use a Capacitor Code Calculator: There are online tools and apps that can help you decipher capacitor codes.
- Check for Manufacturer‘s Markings: Some manufacturers have specific coding systems, so it’s helpful to identify the manufacturer.
- Inspect the Physical Size: Larger capacitors generally have higher capacitance values.
By following these guidelines, you can accurately read the values of film capacitors and select the appropriate components for your electronic projects.
