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, 400 pcs / reel.
5. Inductance tested at 0.1 Vrms @ 100 kHz
6. For non-RoHS parts replace DR prefix with
42- (e.g. DR331-4 becomes 42-331-4)
7. Terminal finish is compliant to RoHS
requirements. Solder in accordance with J-
STD-020C.
