3C95

The standard for broad

temperature range applications

The power loss density versus temperature

curves for 3C95 is very flat and losses vary

little from room temperature to over 100 °C .

This holds for various conditions of frequency

and flux density. Traditionally, power material

is optimized at 100 °C for use in industrial

equipment and special materials are developed

for other temperature ranges. This does not

solve the problem for applications where large

variations in operating temperatures occur for

which the 3C95 material has been developed.

Typical examples are electronic lighting ballast,

and automotive electronics which are mounted in the proximity of 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.The loss level competes with most current Ferroxcube

grades and so does the saturation level. See below for a comparison of the loss density of different materials

with that of 3C95.

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 on the horizon like DC/ DC converters for 42V systems in hybrid vehicles.

• Electronic lighting ballasts

Also here temperatures vary from ambient temperature at lamp ignition (e.g. outdoor lighting) to well over 100°C for a steady state

of operation in certain discharge lamps. Conditions can be especially challenging in hot restart situations.

• Mobile/handheld devices

Working temperatures have to be lower than in industrial equipment and are typically in the 50~60°C range. This range is perfectly covered by 3C95.
