Shielded magnetic circuit reduces leakage flux, Fe
base metal core enables high saturation and
metalized core termination results in excellent shock
resistance.

Notes:
1. Actual temperature of the component during system operation (ambient plus temperature
rise) must be within the standard operating range.
2. The rated current as listed is either the saturation current (@ 20°C) or the heating current
(∆ T
~
40°C) depending on which value is lower.
3. The saturation current is the current at which the initial inductance drops approximately
30% at the stated ambient temperature. This current is determined by placing the compo-
nent in the specified ambient environment and applying a short duration pulse current (to
eliminate self-heating effect) to the component.
4. The heating current is the DC current required to raise the component temperature by
approximately 40°C. Take note that the components’ performance varies depending on
the system condition. It is suggested that the component be tested at the system level, to
verify the temperature rise of the component during system operation.
5. Maximum voltage across terminals to be limited to <40Vdc
