Meeting the Medical Device Directive can be a challenging effort for manufacturers with stringent EMI/EMC requirements that a typically over and beyond the normal generic requirements of ordinary electrical/electronic devices.With the potential of adding new requirements that involve differential noise immunity, the AC power main filter could easily become a key component with both its differential and common mode filtering capabilities. Schaffner not only can provide off the shelf EMC filter solutions but also support manufacturers with their EMC layout from the early stages of new product ideas or designs.
