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. CT319 becomes 42-319 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.
