These properties are measured on stress free toroid cores 25mm/15mm/10mm (outer diameter/
inner diameter/height). Deviations may occur due to product design (large cross section increases
eddy currents thus decreasing the frequency stability) as well as process coating and tumbling.
Winding with thick wire and potting influences the performance as well.
