Zimmer’s Thermo‑TK Tecar system (a representative example for Tecar-style devices), CAP electrodes are ceramic-coated and designed for treating superficial and well‑vascularized tissues. Laboratory documentation confirms that they are available in three distinct sizes:

• Ø 30 mm (small)
• Ø 50 mm (medium)
• Ø 70 mm (large)
  
  

These sizes mirror those of the resistive (RES) electrodes and are typically included as standard accessories with the device.

For other Tecar units like the Tecarpuls II, the same conventions apply: capacitive (and resistive) electrodes are offered in small (30 mm), medium (50 mm), and large (70 mm) sizes.
