Mechanical Outline:

Notes:

1.) All dimensions are in inches/mm

Tolerance:

0.010/0,25 unless otherwise

specified

2.) Inductance tested at 10 kHz, 0.1Vrms

3.) Coplanarity: 0.004/0,102

4.) Tape and reel quantity, 1200 pcs/reel

6.) For Non-RoHS parts, replace CT prefix with -42

e.g. CT319 becomes 42-319

7.) Terminal finish compliant to RoHS requirements.

Solder in accordance with J-STD-020D

8.) Primary DCR (~4mΩ) may cause higher voltage

than typical for current sensing at high current and

higher turns ratios.
