Operating Temperature Range
–55°C to +125°C
Maximum Power Dissipation at 60°C
0.56 W
Note
Current rating is based on 60°C ambient and 125°C
max. operating temperature. The Incremental Current is the
current which causes a maximum change of inductance of
10%.
Marking
API/SMD; HC followed by the dash number with
tolerance letter; date code (YYWWL). Note: An R before
the date code indicates a RoHS component.
