10. Parameters values over operating temperature range are not tested in production, they are guaranteed by design, process control and characterization.
The magnetic characteristics may vary with supply voltage, operating temperature and after soldering.
11. Maximum and minimum hysteresis is guaranteed by design and characterization.
