Peak NanoPlex™ capacitor films deliver f aster, stable pulses at high temperatures, with fewer components and longer life for magnetic fusion. NanoPlex LDF is engineered for magnetic fusion systems that demand high-frequency, high-heat, high-performance pulse delivery. With full energy capacity at 135°C and a low-loss, high-stability architecture, LDF capacitors enable faster shot repetition for injection systems, tighter control, and reduced system complexity, without the thermal, space, or maintenance limitations of traditional banks. - Full energy, zero derating under extreme heat and pulse load - Shorter recovery times boost throughput and consistency - Low self-heating reduces fans, cooling systems, and energy waste - Extended duty under high stress cuts downtime and O&M costs Pulse Stability Rapid Charge/Discharge Thermal Management Energy Efficiency Service Life Precision Firing Without Downtime or Derating - During a fusion pulse, capacitor banks must deliver high current through magnetic field coils that confine the plasma. This generates extreme heat. Traditional BOPP films lose performance above 85°C, compromising energy delivery and reducing pulse precision as repetition rates rise. - NanoPlex LDF maintains full energy capacity up to 135°C without derating, handling intense, repeated fusion shots without drifting or degrading -no oversizing or additional cooling systems required. - Fusion teams get stable, precise performance, even under high heat and heavy load, so they can repeat shots more consistently, improve energy yield, and speed up progress toward commercial fusion. Engineered for Repetition, Stable Operation at Scale - As magnetic-fusion systems push toward higher repetition rates, capacitor banks must charge and discharge in rapid succession. Conventional films degrade quickly under this stress, limiting performance and increasing downtime. - NanoPlex LDF features a low-loss architecture that enables up to 4x faster charge and discharge compared to conventional film. This supports more consistent, high-frequency operation without thermal or structural breakdown. - Shorter recovery times between pulses allow fusion teams to run faster shot sequences, boost pulse reliability, and maintain consistent performance, without increasing replacement cycles or maintenance load. NanoPlex™ LDF Capacitors Last Longer in High Temperatures - With each pulse, conventional BOPP capacitors build internal heat. As temperatures rise past 85°C, they begin to lose capacitance, forcing engineers to add fans, heat sinks, or extra capacitors just to stay within safe limits. - NanoPlex LDF capacitors have a 50% lower dissipation factor than conventional film, producing less self-heating during operation. They remain stable at higher temperatures, even under repeated pulsing. - Fusion teams can reduce their cooling systems, save energy, and simplify thermal design, without sacrificing performance. This means more stable operation, fewer components, and better long-term reliability. Stores More Energy Per Capacitor - To meet modern energy demands, conventional films require more capacitors and longer wiring runs. This inflates system size, increases cost, and makes precise pulse delivery harder to manage. - NanoPlex LDF holds full capacitance up to 135°C, allowing fusion teams to use fewer capacitors without sacrificing performance. Systems are designed to stay cooler and more compact. - Fewer components mean easier installation, reduced material costs, and better pulse control. It also simplifies service and opens the door for more scalable, future-ready fusion systems. Longer LifeSpan, Less Downtime - In fusion systems, repeated heat cycles and electrical pulsing cause BOPP-based capacitors to degrade, leading to frequent replacements, more downtime, and higher maintenance costs. - NanoPlex LDF maintains full energy capacity up to 135°C and resists thermal and electrical fatigue, providing stable, long-term performance under sustained pulsed-power operation. - Fusion teams can reduce scheduled outages, keep systems online longer, and lower total O&M costs, extending service life without compromising performance in high-duty environments.
