*Add “LF” suffix for RoHS requirement. Example: DB1-221LF

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.

• Operating Temperature Range:

-55°C to +125°C

• 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

• Leads tinned to within 0.062 in. of body
