Note1)
The indicated residual voltage is the one after the core hysteresis is removed.
Note2)
Output specifications include 100-Ω output resistance and 1-mA maximum output current.
Note3)
Since residual output is ratiometric output, it varies according to the control power supply value.
Note4)
Code at the end of the model name represents harness specifications.
