4.3. Temperature Compensation
Temperature
TC-Range TC
TCSQ
Coefficient of
Magnet (ppm/K)
The relationship between the temperature coefficient
of the magnet and the corresponding TC, TCSQ, and
TC-Range codes for linear compensation is given in
the following table. In addition to the linear change of
the magnetic field with temperature, the curvature can
be adjusted as well. For this purpose, other TC, TCSQ,
and TC-Range combinations are required which are
not shown in the table. Please contact Micronas for
more detailed information on this higher order temper-
ature compensation.

TC-Calc software to find optimal settings for
temperature coefficients. Please contact
Micronas for more detailed information.
