REDCUBE terminals

REDCUBE is more than a single PCB power terminal. It is a family of high-power connection technologies from Würth Elektronik engineered to simplify power distribution at the board level. Unlike single-technology terminal lines, REDCUBE spans PRESS-FIT, PLUG, SMT, and THR within one portfolio, allowing designers to select the connection technology that best fits their application and manufacturing process. Every variant shares the same DNA: high current-carrying capability, low contact resistance for minimal self-heating, and mechanical performance that holds up in the field.

The four designs at a glance

  • REDCUBE PRESS-FIT
  • REDCUBE PLUG
  • REDCUBE SMD
  • REDCUBE THR

REDCUBE PRESS-FIT

Choose REDCUBE PRESS-FIT when reliability under vibration, thermal cycling, or long-term field exposure is non-negotiable. Pressing a solid pin into a plated through-hole creates a gas-tight cold-weld connection with exceptionally low contact resistance and no solder joint to fatigue. The result is one of the lowest Failure-In-Time (FIT) rates among PCB power connection technologies, with the ability to support current levels up to 500 A, making PRESS-FIT an ideal choice for industrial, energy, transportation, and high-reliability power applications.

REDCUBE PLUG

Choose REDCUBE PLUG when service access, maintenance, or tool-free replacement is part of the design requirement. It combines the proven reliability of a PRESS-FIT cold-weld connection with a pluggable wire-to-board interface, enabling secure locking, tool-free installation, and fast service access. The rugged glass fiber-reinforced housing makes it well suited for demanding and space-constrained applications where minimizing downtime matters as much as delivering power.

REDCUBE SMD

Choose REDCUBE SMT when fully automated pick-and-place and reflow assembly are critical to your manufacturing process. Its compact footprint and large contact area deliver low contact resistance and reduced self-heating while supporting high-density PCB layouts. Available with multiple thread and mounting options, REDCUBE SMT integrates seamlessly into high-volume production environments where power connections must withstand the same reflow process as the rest of the assembly.

REDCUBE THR

Choose REDCUBE THR when you need the mechanical strength of a through-hole connection without sacrificing reflow-compatible assembly. Manufactured from solid material rather than stamped contacts, THR delivers excellent current-carrying capability, high mechanical robustness, and reliable threaded power connections. Designed for automated reflow processing, it provides the durability of through-hole technology while eliminating the need for a separate soldering step.
