MAGNETICS BUTLER,
Standard Gapped Core Tolerances
more information about gapped cores using them, please pages 4.13-4.19. tolerance requirements other than those shown below, please contact factory.
Either depth grind (not both) controlled during production gapped cores. Part numbering gapped cores explained page 1.5. Codes define values. Codes define depths grind. most applications, defining with results inductors with least variation. Electrical measurement inherently more precise, compensation made variability material permeability core geometry.
deep gaps, however, better consistency often results when depth grind specified. such cases, variation finished inductor dominated variation windings, especially number turns low. "Ungapped combination" means asymmetrical gap; entire taken from piece, other piece ungapped. "Gap combination" means symmetrical; half total ground into each piece.

Gapping
Unit Measure When specifying ordering E-Cores gapped important note which cores produced gap-to-gap combination, because gapped pieces assembled achieve Alternatively, ECores provided ungapped-to-gap, ungapped piece must used with gapped part achieve POT, cores sold sets whether combination UG/G. Significant Figures testing limits calculated three significant digits, based nominal value. example, interpreted 96.0 Minimum, 99.0 Nominal, 102.0 Maximum. Correlation Magnetics tests gapped values with full bobbins, usually turns, turns deep gaps. drive level Gauss) frequency enough avoid resonance effects. Measured inductance application vary significantly from theoretical value turns, bobbin fill, leakage effects, resonance effects, elevated drive levels. important user verify correlation between test core specific test being applied inductor transformer. Planar Cores, planar planar cores especially susceptible correlation discrepancies.
