SONG CHUAN
702
Features
ϭ Compact size and low 5mm profile.
ϭ Low power consumption (140mW for single-side stable,
100 to 300mW for latching type).
ϭ Low thermo electromotive force.
ϭ Low magnetic interference enables high-density
mounting.
ϭ Single-and double-winding latching types also available.
ϭ UL and CSA approval.
ϭ Comply with RoHS-Directive 2002/95/EC.
