*Add “LF” suffix for RoHS requirement. Example: DB1-221LF
E
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
• Epoxy-insulated core
