Film Capacitor FAQ
What makes film capacitors unique?
Film capacitors use a thin plastic film as the dielectric, giving them several unique properties:
- Non-polarized design suitable for both AC and DC applications
- Excellent frequency characteristics and low losses
- High insulation resistance and voltage ratings
- Self-healing capability for improved reliability
- Long operational life and stability over time
How does the self-healing property of film capacitors work?
The self-healing mechanism is a key advantage of metallized film capacitors. If a small defect or breakdown occurs in the dielectric:
- The breakdown causes a brief short circuit
- The high current vaporizes a small area of the metallized electrode around the defect
- This creates an insulating area, effectively "healing" the capacitor
- The capacitor continues to function with only a slight reduction in capacitance
What are the main types of plastic films used in film capacitors?
Common dielectric materials include:
- Polypropylene (PP) - Low losses, excellent stability
- Polyethylene terephthalate (PET) - High dielectric constant, compact size
- Polyphenylene sulfide (PPS) - High temperature resistance
- Polytetrafluoroethylene (PTFE) - Excellent high-frequency performance
