Metalized polypropylene film capacitors, also known as MPS capacitors, are widely used in various electronic devices and applications. These capacitors are made by depositing a thin metal layer, usually aluminum, onto a polypropylene film. The metal layer acts as the electrode, while the polypropylene film serves as the dielectric.
MPS capacitors have several advantages over other types of capacitors. First, they have excellent self-healing properties, which means that if the dielectric is punctured or damaged, the metal layer will vaporize and create a small gap, preventing further damage and maintaining the capacitor's functionality. This self-healing property makes MPS capacitors highly reliable and durable.
Second, MPS capacitors have low equivalent series resistance (ESR) and equivalent series inductance (ESL),
which means that they have low losses and can provide high-quality filtering and energy storage. This makes them suitable for applications that require high performance and efficiency, such as power supplies, motor drives, and audio equipment.
Furthermore, MPS capacitors have a high insulation resistance and can withstand high voltages, making them suitable for high-voltage applications. They also have a wide temperature range, typically from -55°C to +105°C, which allows them to operate in extreme environments.
In terms of applications, MPS capacitors are commonly used in power electronics, where they are used for power factor correction, snubber circuits, and DC link applications. They are also used in audio systems for coupling and decoupling, as well as in lighting systems for ballast capacitors.
In conclusion, MPS capacitors are a reliable and versatile type of capacitor that offer excellent self-healing properties, low losses, and high voltage
capabilities. They are widely used in various electronic applications and provide high performance and efficiency.
