Reliable Energy Storage for Modern Power Electronics
#
DC-Link capacitors are essential components in advanced power electronic systems, providing stable energy storage and voltage smoothing in demanding environments. The ESDS series, developed with dry-type, metallized polypropylene film technology, is engineered to deliver high energy density (up to 0.25J/cc) and robust performance across a wide range of applications.
Key Features and Benefits
#
Dry-Type, Metallized Film Construction: Utilizes self-healing metallized polypropylene film, ensuring low losses and long-term reliability.High Dielectric Strength: Special polymeric dielectric composition supports operation up to +85°C, maintaining performance in challenging conditions.Low Self-Inductance: With an ESL of less than 100nH, these capacitors are optimized for high-frequency applications.Extended Lifetime: Designed for over 100,000 hours of operation, with a failure rate below 100 FIT.Natural Cooling: Efficient heat dissipation without the need for forced cooling systems.
Typical Applications
#
Electro-transport systems
Substations
