Inductors and Flybacks.
THINZ – MPP THINZ® are extremely low height (<1 mm) self-shielded
power inductor cores, allowing finished inductor heights in the 1.5 mm to
2 mm range. THINZ come in 5 sizes with O.D.s ranging from 3.1 mm
(0.120") through 7.9 mm (0.310") and four permeabilities: 125µ, 160µ, 200µ
and 250µ.

Machined Prototypes
and Custom Components
Magnetics’ world-class materials offer unique and powerful advantages to
almost any application. An even greater competitive edge can be gained
through innovations in new core shapes and custom geometries, and
Magnetics is poised to help. Our Rapid Prototyping Service can quickly
make a wide variety of core shapes in ferrite, MPP, High Flux, or Kool
Mu®. The time between receipt of your drawing and delivery of the parts
to you is usually less than 10 days. This quick turnaround time results in
a shorter design period, which gets your product to market faster. Plus,
our application engineers may be able to provide design assistance that
could lead to a lower piece price. To learn more about how our Rapid
Prototyping Service can help you shorten your design cycle, contact a
Magnetics Application Engineer.
Strip Wound Cores
Tape wound cores are made from high permeability alloys of nickel-iron,
grain oriented silicon-iron. The alloys are known as Orthonol®, Alloy 48,
Square Permalloy 80, Supermalloy and Magnesil®. Cores are available in
more than 50 standard sizes. For a wide range of frequency applications,
materials are produced in thicknesses from 0.013 mm (1/2 mil) through
0.356 mm (14 mils). Cases are robust nylon boxes, rated for 200° C
continuous operation and 2000 voltage minimum breakdown.
APPLICATIONS – Magnetic Amplifiers, Reactors, Regulators, Static
Magnetic Devices and Current Transformers.
Miniature Tape Wound Bobbin Cores are manufactured from Permalloy 80
and Orthonol ultra-thin tape (0.000125" to 0.001" thick). They are available
in widths from 0.031" to 0.250" (wider on special request). Wound on
non-magnetic stainless steel bobbins, core diameters are available down
to 0.050", with flux capacities as low as several maxwells. Magnetics’
sophisticated pulse test equipment reproduces most test programs and
can measure accurately in the millivolt-microsecond region.
