4 ) The data shown below can be sorted by clicking each column header.Click once again to sort in reverse order.

5) Rated Current is based on a 60 deg C temperature rise at an ambient temperature of 40 deg C. KoolMu/Sendust versions can operate to over 200 deg C. Iron Powder cores may exhibit thermal aging and that limits the operating tempertaure to 100 deg C.

6) Helical wire used on both KoolMu/Sendust and Iron Powder versions has Kapton insulation and can withstand a temperature of 220 deg C.
