+ | **Flux band** - a conductive loop, effectively a [[short-circuited turn]], wrapped closely around the outside of an [[electronic transformer]] to reduce the effect of the [[flux fringing|fringing]], | ||

+ | The flux band couples electromagnetically to the stray flux, generates opposing currents and partially reduces [[radiated emission|radiated emissions]]. But because it is located on the outside of the returning [[limb|limbs]] of the magnetic core it does not impact on the main operation of the transformer. | ||
+ | |||
+ | The flux band can be connected to ground or one of the windings (e.g. primary) to help in reduction of electrostatically coupled interference. | ||
+ | |||
+ | The presence of a conductive flux band might compromise the [[creepage and clearance distance]]s, | ||
