SUGGESTED PAD LAYOUT
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
5.) Terminating resistor (RT) calculated:
RT = (NTURNS / IPRI) * VREF
6.) For Non-RoHS parts, replace CT prefix with -42
e.g. CT319 becomes 42-319
