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.
