Metal Alloy Inductors DFE252012C Recommended patterns Inductance Range: 0.47~10H (Unit: mm) (Unit: mm) FEATURES Miniature size: 2520 footprint (2.5mmx2.0mm) and low profile(1.2mm Max. height) The use of magnetic iron powder ensure capability for large current. The use of Flat wire for Low DC resistance. Magnetically shielded, low audible core noise. Reflow solderable. Operating temperature : -40+85C STANDARD PART NUMBERS (2.52.01.2mm Max.) -40+85C TYPE DFE252012C (Quantity/reel; 3,000 PCS) Part Number Inductance L(H) Tolerance (%) 1239AS-H-R47M=P2 1239AS-H-1R0M=P2 1239AS-H-1R5M=P2 1239AS-H-2R2M=P2 1239AS-H-3R3M=P2 1239AS-H-4R7M=P2 1239AS-H-6R0M=P2 1239AS-H-6R8M=P2 1239AS-H-100M=P2 0.47 1.0 1.5 2.2 3.3 4.7 6.0 6.8 10 20 20 20 20 20 20 20 20 20 Test Frequency (MHz) 1 1 1 1 1 1 1 1 1 (1) Inductance is measured with a LCR meter 4284A (Agilent Technologies) or equivalent. Test frequency at 1MHz (2) DC resistance is measured with 34420A (Agilent Technologies) or 3541(HIOKI). (Reference ambient temperature 20C) (3) Maximum allowable DC current is that which causes a 30% inductance reduction from the initial value, coil temperature to rise by 40C whichever is smaller.
