*Add “LF” suffix for RoHS requirement. Example: 050AT1002HLF

VERTICAL CONFIGURATION

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:

E DIA

• 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

• Excellent Electromagnetic Shielding

HORIZONTAL CONFIGURATION

E DIA

• Leads are stripped and tinned to within 0.062 in.
