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-020D
