Film capacitors are a type of electronic component using plastic films (e.g., polypropylene, polyester) as dielectric materials. They are non-polarized capacitors with high insulation resistance, low loss, and excellent long-term stability. These capacitors play critical roles in power electronics, automotive systems, renewable energy, and consumer devices due to their reliability and high voltage-handling capabilities.
| Type | Functional Characteristics | Application Examples |
|---|---|---|
| Polyester (PET) | Low cost, compact size, moderate temperature stability | General-purpose circuits, consumer electronics |
| Polypropylene (PP) | High voltage resistance, low dielectric loss, excellent thermal stability | Power supplies, motor drives, EV charging systems |
| Polycarbonate (PC) | High precision, low moisture absorption | Medical devices, aerospace instrumentation |
| Polyphenylene Sulfide (PPS) | High-temperature endurance, flame retardant | Automotive electronics, industrial automation |
| Polyimide (PI) | Ultra-high temperature resistance (up to 200 C), compact design | Aviation systems, downhole drilling equipment |
Film capacitors typically consist of metalized plastic films wound or stacked into a cylindrical/rectangular core. The dielectric thickness ranges from 1-10 m, with electrode materials like zinc or aluminum. The assembly is encapsulated in epoxy resin or plastic housings. Key structural elements include:
| Parameter | Description | Importance |
|---|---|---|
| Capacitance Range | 0.1 nF - 100 F | Determines energy storage capacity |
| Rated Voltage | 50 V - 10 kV | Defines operational safety limits |
| Capacitance Tolerance | 1% to 20% | Affects circuit precision |
| Dissipation Factor | 0.0001 - 0.05 | Indicates energy efficiency |
| Insulation Resistance | 10^9 - 10^12 | Reflects leakage current performance |
| Operating Temperature | -55 C to +155 C | Dictates environmental adaptability |
| Temperature Coefficient | 50 to 400 ppm/ C | Impacts stability under thermal stress |
| Stability | C/C < 2% over 10 years | Long-term reliability indicator |
Main industries and equipment:
| Manufacturer | Representative Product | Key Features |
|---|---|---|
| TDK Corporation | B32656 series | PP film, 480 F/1200 V for industrial inverters |
| KEMET | C4AZ-X7R4U3D106KE | Automotive-grade DC link capacitor |
