CHARACTERISTICS
Description:
SMD (unshielded) power inductor.
Applications:
Ideal for a variety of DC/DC converter
applications and low profile use.
Operating Temperature:
-40°C to +85°C
IDC:
Maximum allowable DC current is that which causes a 10%
inductance reduction from the inital value, or coil temperature to
rise by 40°C, whichever is smaller.
Inductance Tolerance:
±20%
Testing:
Inductance is tested on an HP4285A at 100KHz, 0.25V
Packaging:
Parts are marked with inductance code.
Marking:
Tape & Reel.
Miscellaneous:
RoHS Compliant.
Additional Information:
Additional electrical & physical
information available upon request.
Samples available. See website for ordering information.
