RM Power Switchmode Transformers
This spec sheet is available in printable format.

RM Photo Features:

  • Good for gapped or ungapped applications.
  • Side pin configuration gives best reliability and manufacturability.
  • Less ideal for applications involving IEC spacing requirements.

 

How to choose your model:

  • Use the “sizing factor” previously calculated and the frequency to locate a point on the chart.
  • Choose the model # whose line is above the located point.
  • Note: During the design process, the actual sizing factor may vary from the assumptions used here.
