All part numbers provide 10% tolerance on inductance

Custom designs are available to meet your specic requirements; please contact factory

*Add “LF” suffix for RoHS requirement. Example: 050KM1002HCLF

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
