B252LF

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.

 STANDARD POWER INDUCTORS - THRU HOLE

All part numbers provide 10% tolerance on inductance

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