1
Unshielded and small in size with high energy storage
and low resistance
Notes:
Suitable for notebook computers and other portable
handheld devices
High performance and self-leaded design for surface
mounting applications
Inductance range from 1 to 68 micro H
RoHS compliant versions are available
2. Rated D.C. current indicates the current when the inductance is 10% lower than its initial value at D.C. superposition,
or the current when at T=40°C, whichever is lower.
1. Inductance is tested at 1MHz.
3. Operating temperature range: -30°C to +100°C.
4. Contact EEMPL for RoHS compliant version availability.
5. The part temperature (ambient temperature + temperature rise) should not exceed the upper limit of the operating
temperature 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.
