4. Heat Rated Current (Irms) will cause the coil temperature rise approximately
Δt≦40
℃
(keep 1min.).
5. Saturation Current (Isat) will cause L0
to drop
≦
20% typical.
(keep
quickly).
6. The part temperature (ambient + temp rise) should not exceed 125
℃
under worst case operating conditions.Circuit design,component,PCB trace size and
thickness,airflow and other cooling provisions all affect the part temperature. Part temperature should be verified in the end application.
7. Special inquiries besides the above common used types can be met on your requirement.
