MS90542 - PHENOLIC CORE

MS14052 - POWDERED IRON CORE

Suffix “K” for 10% tolerance

Optional tolerances available; please contact factory

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

*Add “LF” suffix for RoHS requirement. Example: 21M470KLF

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.
