DATATRONIC: 28151 Highway 74, Romoland, CA 92585
All dimensions are in inches/mm
Tolerance: 0.010/0,25 unless otherwise
specified
Inductance tested at 10 kHz, 0.1Vrms
Coplanarity: 0.004/0,102
Tape and reel quantity, 1200 pcs/reel
Terminating resistor (RT) calculated:
RT = (NTURNS / IPRI) * VREF
For Non-RoHS parts, replace CT prefix with -42
e.g. CT321 becomes 42-321
Terminal finish compliant to RoHS requirements.
Solder in accordance with J-STD-020D
Primary DCR (~4mΩ) may cause higher voltage
than typical for current sensing at high current
and higher turns ratios.
