Coils are rated in millihenrys (mH). When you read Coil Value .13, this means .13 mH. This chart is a combination of FERRITE BAR COILS and FERRITE BOBBIN COILS in values that are suitable for many
situations. These coils are appropriate for systems using up to
approximately
50 watts. For higher power situations go to ECONOMY,
AIR
CORE COILS or IRON CORE
COILS.
