SMT POWER INDUCTORS
Volta-5 Series
Notes from Tables
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 current which causes the
inductance to drop by 10% at the stated ambient temperatures
(-40°C, 25°C, 125°C). This current is determined by placing the
component in the specified ambient environment 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 tempera-
ture of the part to increase by approximately 40°C. This current
is determined by mounting the component on a PCB with .25"
wide, 2 oz. equivalent copper traces, and applying the current
to the device for 30 minutes. In the series hookup mode, the
resistance of the interconnection needs to be taken into
account when calculating temperature rise.
4. In high volt*time applications additional heating in the
component can occur due to core losses in the inductor
which may neccessitate derating the current in order to limit
the temperature rise of the component. In order to determine
the approximate total losses (or temperature rise) for a given
application both copper losses and core losses should be
taken into account.

The temperature of the component (ambient temperature +

temperature range.
