*Add “LF” suffix for RoHS requirement. Example: 26HF1002SMLF
Gowanda designates a component RoHS-compliant by adding “LF” (lead free) to the part number.
These LF components meet the ≤ .1% lead requirement and they are compatible with 260°C soldering processes.

NOTES:
SIDE VIEW
• Operating Temperature Range:
-55°C to +130°C
• Current Rating is based on a 35°C temperature
rise at an ambient temperature of 90°C
• Incremental Current is the approximate value
that will cause a percentage drop in inductance
as indicated in the table
• Excellent electromagnetic shielding
