SHIELDED SMD INDUCTOR DR331-7 SERIES

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, 2000 pcs / reel.

5. Inductance tested at 0.1 Vrms @ 100 kHz For non-RoHS parts replace DR prefix with 42- (e.g. DR331-7 becomes 42-331-7) 6. Terminal finish is compliant to RoHS requirements. Solder in accordance with J-STD-020C
