Press-Fit Aluminum Electrolytic Capacitors

  • E​liminates manufacturing problems of soldering onto thick PCB copper tracks which act as heat-sinks
  • Eliminates fractured solder joints/cold-solder
  • Removal of the solder operation allows for easy insertion after the production washing process
  • Ability to exchange components in the field
  • ​Custom optimization of construction available for application-specific balance between required life, temperature, ripple current and physical size
  • Frequency converters
  • Solar inverters
  • Advanced energy storage systems
  • Switch mode power supplies
  • Other high reliability, long life applications
