ALPS works with Tohoku University on magnetic alloy
ALPS Green Devices has developed a range of power inductors with a core material which is a magnetic amorphous alloy created through joint research between ALPS Electric and Tohoku University.
It is a new magnetic material used in place of the most common core material, ferrite, and iron powder.
Dubbed Liqualloy, the core material will minimise power loss during conversion, said the supplier.
The GLMH series also employs an integrated coil-terminal structure, applying original technology for high-precision forging of thin coil wire.
With the coil wire doubling as the terminals, DC resistance is reduced by 10 to 20% compared to conventional types with the same level of inductance.
This structure keeps DC resistance tolerance to ±5% and reduces heat generation during high-load operation, thereby further improving on the high current compatibility of earlier products.
