Magnetic cores

Dust cores: MOLYPERMALLOY (MPP) - MAGNETICS production.

Dust cores type: Alloy- Magnetics Molypermalloy (MPP) are toroidal cores with dissipate air gap. 
They are made of:79% nickel, , 17% iron, and 4% molybdenum alloys, which allow to obtain lowest core power losses, in comparison to any other Dust material. MPP cores have many great magnetic properties like high resistivity, small hysteresis, low eddy currents, great stability after saturation. 
This is magnetic material, which provide low inductor power losses. MPP cores characterise with high induction and temperature stability.

DUST CORES MAGNETICS HIGH FLUX

This are toroidal cores with dissipate air gap made from alloys:  50% nickel - 50% iron. Those cores characterise with high saturation induction.
High Flux have advantages, which make them very useful in high power, high voltage and frequency applications. 
Core saturation inductance is on 1.5T level, in comparison to 0.75 of standard MPP or 0.45 for ferrites. 
Power losses are lower than in standard type "iron Dust" cores.

CORES KOOL Mμ®

Dust cores with dissipate air gap are made from iron alloys. They characterise with very low losses for a wide frequency range and high magnetic parameters stability.
Close to zero magnetostriction makes them ideal for elimination of arduous noises at high frequencies.
In high frequency applications, losses in core made from iron alloys, may be the main reason of temperature rise. This is why, Kool Mμ cores are ideal for above applications, because their losses are smaller, and therefore their temperature rise and dimensions are much smaller.

KOOL Mμ®  CORES  E SHAPE

E - shape cores with dissipate air gap have properties which make them useful in wide range of applications for example: PFC correction, chokes, flyback converters. Core induction saturation level 1,05 T. allows to store more energy in comparison to E shape ferrite cores, which leads to core dimensions decrease. Kool Mμ E shape cores are pricey competitive. They have great thermal properties.

XFLUX ™ Cores

Magnetics cores are made from: 6, 5 % silicon and iron dust. Material is resistant for high temperatures, without temperature ageing. XFLUX  offers lower power losses than in normal dust cores.
XFLUX soft saturation characteristic offers advantages in comparison to ferrite cores. This cores are ideal for low and medium frequency chokes where induction on peak is not critical.

MPP THINZ ™ or  Molypermalloy dust cores are made from: 81% nickel, 17% iron and 2% molybdenum. They offer highest magnetic permeability, and high saturation inductance. They characterise with very small dimensions. They are temperature stable, and have small power losses.

Application:

Magnetics dust cores are used in high power circuits, especially in impulse power supplies, filters and resonant circuits.
