NOTES:
1. The I
rated
is either 85% of the I
saturation
or the I
heating
depending which is lower.
2. The I
saturation
is the current which causes the inductance to drop by 15% of its nominal value.
3. The I
heating
is the current which causes the temperature of the part to increase by approximately 45°C.
Product performance is limited to specified parameters. Data is subject to change without prior notice.
