4.3. Temperature Compensation
The relationship between the temperature coefficient
of the magnet and the corresponding TC and TCSQ
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 and TCSQ combi-
nations are required which are not shown in the table.
Micronas also offers a software named TC-Calc to
optimize the TC and TCSQ values for each individual
application based on customer measurement results.
Please contact Micronas for more detailed information.
