Comments

  • Do not underrate parasitic effects when using common mode chokes. It was the most important point to reduce these dues when developing WE-CMB series. The perfect core/winding-ratio enables very high currents at comparable areas, anyhow the inductance is sufficient. The adjusted wire gauge realises low heating.
