Capacitors
High-voltage capacitors from specialist manufacturers deliver reliable performance for your demanding industrial and high-power applications. With a wide range of DC link, snubber, high-voltage, energy storage, and pulse capacitors, your systems benefit from stable operation, efficient energy management, and long-term durability. Selecting the right components helps maintain consistent performance, minimise downtime, and support the reliability of your critical equipment and operations.
DC Link Capacitors
DC Link Capacitors provide you with customised and standard solutions featuring extremely low ESR and ESL. You can enhance performance and reliability with high-performance DC link test kits with advanced cooling, supporting your power conversion, storage, and high-performance DC applications while optimising efficiency and operational control.
Snubber Capacitors
Designed to protect your power semiconductors from damaging voltage spikes and high dV/dt stress, our snubber capacitors support reliable operation in demanding switching applications. They minimise transient overvoltage, reduce switching losses and help extend the lifespan of your IGBTs, MOSFETs and other high-speed devices. With low ESR, ESL and high pulse current capability, they deliver stable, repeatable performance in pulsed power and advanced power electronics systems.
High Voltage Capacitors
High-voltage capacitors store and release energy rapidly, helping you stabilise your industrial, renewable, and power distribution systems. They smooth voltage fluctuations, improve energy efficiency, and protect your equipment, giving you reliable performance, operational stability, and safe, consistent operation across all your high-voltage applications.
