*Add “LF” suffix for RoHS requirement. Example: DB4-102LF
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.

• Current Rating is based on a 35°C temperature
rise at an ambient temperature of 90°C
• Saturation Current is the approximate value
that will cause a 10% drop in inductance as
indicated in the table
