Film Capacitors

1. Overview

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.

2. Main Types and Functional Classification

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

3. Structure and Composition

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:

Dielectric layer (plastic film)
Metallized electrode patterns
Termination electrodes (sprayed metal contacts)
Protective outer coating

4. Key Technical Parameters

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

5. Application Fields

Main industries and equipment:

Power electronics: AC/DC converters, frequency inverters
Automotive: Electric vehicle (EV) on-board chargers, battery management systems
Consumer electronics: LED lighting, plasma TVs
Industrial: Uninterruptible power supplies (UPS), welding machines
Renewable energy: Solar inverters, wind turbine converters

6. Leading Manufacturers and Products
