TUNS300F12 Frequently Asked Questions (FAQs)

  • Cosel recommends a PCB layout with a large copper area for heat dissipation, and a minimum of 2oz copper thickness. A thermal via array under the module can also improve heat transfer.
  • To ensure reliable start-up and shutdown, Cosel recommends a soft-start circuit to limit inrush current, and a shutdown circuit to discharge the output capacitors. Consult the application note for specific guidance.
  • Cosel provides derating curves in the application note, which show the maximum output power and current at elevated temperatures. These curves help ensure reliable operation within the specified temperature range.
  • Yes, the TUNS300F12 can be used in redundant or N+1 configurations. However, Cosel recommends consulting with their application engineers to ensure proper implementation and to discuss specific requirements.
  • Cosel recommends using a CISPR 11 Class B or Class A EMI filter, depending on the application's electromagnetic compatibility requirements. Consult the application note for specific guidance on filter selection and implementation.
