Each application may contain other variables which must be considered in part selection, such as temperature effects, waveform distortion, etc. API Delevan Sales/Engineering is available to provide information as needed to fit each application.

When significantly greater AC flux density is present, it becomes necessary to consider its effect on both core loss and permeability (inductance). All data points, on the above graphs, that exceed the rated DC current specified for a 55°C rise from a 25°C ambient are for design reference only and are not intended to imply continuous use at those DC current levels. 270 Quaker Rd., East Aurora NY 14052 • Phone 716-652-3600 • Fax 716-652-4814 • E-mail: apisales@delevan.com • www.delevan.com 8/2021
