FERROXCUBE introduces a new

power material , suitable for a broad

temperature range : 3C95. The power

loss density versus temperature

curves are very flat. Losses vary

little from room temperature to

over 100 C. This holds for various

conditions of frequency and flux

density. Traditionally, power materials

are optimized at 100 C for use in

in-house equipment. Special materials

are developed for other temperature

ranges. This doesnt solve the problem

for other applications where large

variations in operating temperatures

occur, for which the new material

3C95 has been developed. Typicalexamples are electronic lighting

ballasts and automotive electronics

mounted in the neighbourhood of the

engine.

FERROXCUBE has started the

introduction of the new material

in regular core shapes for power

applications, such as E, U, EFD, ER,

EQ, PQ, RM and planar shapes.

Samples are available on request.

The loss level competes with most

current Ferroxcube grades and so

does the saturation level. See below

a comparison of the loss density

of different materials with that of

the new material 3C95. A complete

specification can be found on the next

page.

Applications for 3C95 can be found in

various areas : Automotive electronics near the

engine. Temperatures vary from

ambient temperature at motor start,

which might be below zero, to far

over 100 C for a steadily running

motor. More power applications

appear at the horizon like dc/dc

converters for 42 V systems in hybrid

vehicles.

Electronic lighting ballasts

Also here temperatures vary from

ambient temperature at ignition (think

about outdoor lighting) to far over

100 C for steady state operation

in certain discharge lamps. Especially

for a hot restart, conditions can be

challenging.

Mobile / handheld devices

Working temperatures have to be

lower than in stand alone equipment

and lie more around 50 - 60 C. Thisrange is perfectly included in 3C95

working conditions.
