Stable Power Starts with the Right DC-Link Capacitors

Power electronics are becoming more powerful, more compact – and increasingly demanding. This is exactly where DC-link and snap-in capacitors come into play: they ensure stable and reliable system operation, even under highly dynamic load conditions.

Whether in inverters, power supplies or on-board chargers – modern applications require clean voltage profiles and reliable DC-link buffering that can provide sufficient energy at any time.

Why DC-Link Capacitors Are Essential

DC-link capacitors play a key role in power electronic systems. They stabilize the output voltage of rectifiers, store energy, and compensate for load peaks and voltage fluctuations. This prevents sudden voltage drops or spikes – directly improving efficiency, lifetime, and overall system reliability.

Solutions Tailored to Your Application

At Beck Elektronik, you will find a carefully selected portfolio from leading manufacturers – perfectly matched to the requirements of modern power electronics:

  • Snap-in capacitors (CapXon, Chemi-Con) with high capacitance values in the range of several 1,000µF and voltage ratings from 450 to 700V
  • Snap-in pulse capacitors (CapXon) designed for short-term high energy delivery and very high discharge currents
  • Film DC-link capacitors (ISKRA, ZhongXing) for applications up to 1,200V and capacitances exceeding 100µF

Our portfolio is continuously expanded with new series, focusing on higher power density, extended lifetime, and optimized designs.

Together, we will find the solution that best fits your application.
