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.
