简体中文Our Advanced Coating Technology
At Jiangsen Electronics, we take pride in our state-of-the-art Leybold Optics coating machines. We operate 6 highly efficient Leybold Optics machines, imported from Germany, to produce world-class metallized polypropylene films. These machines are renowned for their precision, high deposition rates, and ability to create films with exceptional uniformity and durability.
One of our Leybold Optics coating machines at Jiangsen Electronics.
The Leybold Optics machines enable us to maintain a dust-free, moisture-controlled environment, ensuring optimal quality and performance of our capacitor films. With their advanced technology, we achieve higher efficiency and precision, which sets us apart in the capacitor film industry. These machines support our goal of producing capacitor films that meet the stringent requirements of industries such as renewable energy and automotive applications.
Capacitor Types
Below is a comparison of capacitor films against alternative capacitor technologies to highlight their advantages:
| Feature | Capacitor Films | Aluminum Electrolytic Capacitors | Ceramic Capacitors |
|---|---|---|---|
| Dielectric Material | Polypropylene (PP), Polyester | Electrolyte | Ceramic |
| Voltage Tolerance | High (up to 2000V) | Medium (500-650V) | High (up to 1000V) |
| Thermal Resistance | Excellent (up to 125°C) | Moderate (85°C) | Varies (up to 150°C) |
| Applications | Inverters, DC-Links, Renewable Energy | DC Support, Basic Power Supplies | High-Frequency Circuits |
| Lifetime | Long (self-healing) | Shorter (limited by electrolyte evaporation) | Moderate |
| Flexibility | High (custom shapes and sizes) | Low | Low |
Applications of Capacitor Films
1. Automotive Industry
With the rise of electrification, capacitor films have replaced aluminum electrolytic capacitors in new energy vehicles. The table below demonstrates why capacitor films are preferred:
| Criteria | Capacitor Films | Aluminum Electrolytic Capacitors |
|---|---|---|
| Energy Density | Higher, suitable for compact designs | Lower |
| Voltage Handling | 650V and above | Limited to 500V |
| Durability | Excellent, withstands voltage surges | Susceptible to damage over time |
Future Trends and Innovations
The ongoing developments in capacitor films include:
- Miniaturization: Designing compact capacitors for limited spaces in advanced electronics.
- High-Temperature Resistance: New films capable of operating above 150°C.
- Environmentally Friendly Materials: Research into biodegradable dielectric materials.
