KT11835
transponder coil (Rx)
features
•
Transponder coil is arranged with
electrode in the long side of the part,
and covered with molding resin
•
Excellent high Q and high sensitivity, because neither
the electrode nor the land pattern disturb the coil flux
•
Strong resistance to vibration, shock and substrate bend
test by 4 electrode terminals structure and the molded resin
•
Small inductance change to environmental
temperature change
•
Marking: Black body color
•
Products meet EU RoHS requirements
•
AEC-Q200 Qualified
