Notes
1. The rated current as listed is either the saturation current or the heating current
depending on which value is lower.
2. The saturation current is the typical current which causes the₆i₀nductance to drop by
20% at the stated ambient temperatures (25°C and 100°C). This current is determin^.e⁵d⁸³
by placing the component in the specified ambient environm5e0nt and applying a short
duration pulse current (to eliminate self-heating effects) to the component.

3. The heating current is the DC current which causes the part t⁴em⁰ peratur.e393
to increase by approximately 40°C.
