MECHANICAL SPECIFICATIONS

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
