Document 181-1 SMTPowerInductors-DO5022H Series We now offer an improved version of this series: DO5010H. It is electrically equivalent, has a smaller footprint and comes in more inductance values. We will, however, continue to produce the DO5022H indefinitely. This family of inductors was designed for high current, low-voltage DC-DC converter applications, especially the latest generation of 3.3 V microprocessors. Current ratings up to 15 A rms and saturation currents up to 30 A are available. These parts are only 8,0 mm high and have exceptionally low DC resistance thanks to the use of heavier gauge wire. The DO5022H Series has been optimized for reliable surface mounting with a large flat top and self-leaded design. In addition to the standard parts shown, custom values are available. 1 Part Number1 0.640 max 16,26 DO5022H-781ML_ DO5022H-152ML_ DO5022H-222ML_ DO5022H-332ML_ DO5022H-392ML_ 0.500 12,7 DO5022H-472ML_ DO5022H-602ML_ DO5022H-782ML_ DO5022H-103ML_ DO5022H-153ML_ 0.315 max 8,00 0.880 max 22,35 0.125 3,18 0.565 14,35 0.561 min 14,25 0.340 8,64 Part Marking 1st significant digit Internal code XXX Multiplier (or) X 2nd significant digit 0.78 1.5 2.2 3.3 3.9 4.7 6.0 7.8 10 15 2.6 4.0 6.1 8.6 10 2SRF3 typ 2Isat4 (MHz) (A) 2Irms5 (A) 156 100 75 60 55 30 25 20 17 15 15 15 12 10 9.0 40 35 35 28 20 13 12 11 10 8 8.4 7.5 7.5 6.0 4.4 14 17 18 26 32 DO5022H-153MLD Recommended Land Pattern 0.125 max 3,18 0.815 max 20,70 (µH ±20%) DCR max (m⏲) 1.
