Marking
The inductor is marked with a 3-digit code
Example - -1.0→1R0
Note：Using ink for marking
Notes about electrical characteristics:
1. All test data is referenced to 25 °C ambient.
2. Operating temperature range - 55 °C to + 125 °C.
3. Idc(A):DC current (A) that will cause an approximate
ΔT
of 40 °C
(reference ambient temperature is 25
°C).
4. Isat(A):DC current (A) that will cause L0 to drop approximately 30 %.
5. The part temperature (ambient + temp rise) should not exceed 125 °C under worst case operating conditions. Circuit
design, component placement, PWB trace size and thickness, airflow and other cooling provisions all affect the part
temperature. Part temperature should be verified in the end application.
