NOTES:

1. Dimensions are shown in inches/millimeters

Unless otherwise specified, tolerance

= Inches: ±0.010

= Millimeters: ±0,25

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, 2000 pcs / reel.

5. Inductance tested at 0.1 Vrms @ 100 kHz

6. For non-RoHS parts replace DR prefix with

42- (e.g. DR331-2 becomes 42-331-2)

7. Terminal finish is compliant to RoHS

requirements. Solder in accordance with J-

STD-020C.
