*Add “LF” suffix for RoHS requirement. Example: 180KM1002SMLF
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:
• Operating Temperature Range:
-55°C to +130°C
• Current Rating is based on a 40°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
