NOTES:
1. Dimensions are shown in inches/millimeters
2. Unless otherwise specified, tolerance = Inches: ±0.012
= Millimeters: ±0,30
3. Isat based on the inductance being 90% of its initial value
4. Irms based on a temperature rise of 20°C
5. For non-RoHS parts replace DR prefix with 42- (e.g. DR217-4 becomes 42-217-4)
6. Terminal finish is compliant to RoHS requirements
