In an era of rapid technological advancement, smart appliances are no longer just about convenience—they now shoulder the critical mission of energy saving. However, as smart functions continue to expand, these devices consume more energy, placing new demands on batteries and power systems. To achieve superior energy efficiency, electronic design must strike a balance between size, power consumption, durability, and stability—where film capacitors play a pivotal role. With their ultra-low loss, excellent high-voltage endurance, and long operational life, film capacitors have become indispensable components in smart appliances.
Fundamentals and Applications of Film Capacitors
- Dielectrics and Material Properties
Film capacitors commonly use metallized plastic films (such as polypropylene, PP, or polyester, PE) as dielectrics. Among them, polypropylene (PP) film is the preferred material for industrial applications due to its low moisture absorption and high thermal stability.
- Electrical Performance Advantages
Film capacitors feature extremely low equivalent series resistance (ESR) and equivalent series inductance (ESL). As a result, they significantly reduce energy loss in high-frequency or pulse applications, improving overall efficiency.
- Diverse Application Scenarios
-
Motor Starting and Running:
In air conditioners, refrigerators, and washing machines, film capacitors assist in motor start-up and stable operation, greatly enhancing efficiency.
