A principal caracter\u00edstica dos adaptadores de alimenta\u00e7\u00e3o automotiva reside em seu ambiente de trabalho adaptativo extremamente severo.

Em termos de projeto estrutural mec\u00e2nico, as fontes de alimenta\u00e7\u00e3o automotivas t\u00eam altos requisitos de resist\u00eancia a impactos e quedas.
