MECHANICAL SPECIFICATIONS

NOTES:

1.

Dimensions are shown in inches/millimeters

Unless otherwise specified, tolerance

= Inches: ±0.010

= Millimeters: ±0,30

2.

Isat based on the inductance being 90% of its initial value

3.

Irms based on temperature rise of 40°C

4.

Tape & Reel Packaging

5.

Inductance tested at 0.1 Vrms @ 100 kHz

6.

For non-RoHS parts replace DR prefix with 42- (e.g. DR331-5 becomes 42-331-5)

7.

Terminal finish is compliant to RoHS requirements. Solder in accordance with J-STD-020C.
