Notes:
1. The current rating (Irms) is based upon the temperature rise of the component and represents the rms current which will cause a typical temperature rise of 40ºC.
2. The peak current is the current which will typically cause a 20% drop in the dierential mode inductance. The peak current should not be exceeded in the application as it will
reduce the CM and DM rejection of the component.
3. The temperature of the component (ambient plus temperature rise) must be within the stated operating temperature range.
4. The PA4040.XXXNL is designed to provide 3.0mm of safety spacing (creepage and clearance distance) between windings and 1.5mm of safety spacing (creepage and clearance
distance) between both windings and core.
