 &lt;br /&gt;
While electrical specifications of cores vary by model and manufacturer, the main cause for variation is the different voltage and frequency of the country in which the microwave was built. &lt;br /&gt;
Inputs of 100V/110V/120V/220V/230V/240V as well as outputs from 500V to 1200VA variations of the transformer exist in countries that use either 50hz or 60hz power. A transformer core rated for 60hz is smaller than one rated for 50hz for the same reasons a smaller bell produces a higher pitch.&lt;/div&gt;</summary>
