Document 188-1 SMT Power Inductors – DS5022P Series The DS5022 Series of magnetically shielded power inductors is designed for the higher current requirements of portable computers, video recorders and other DC-DC conversion applications. They feature saturation current ratings as high as 18 Amps and rms current ratings up to 6.5 Amps. Low DC resistance (as low as 0.040 Ohms) keeps power losses to a minimum. For new designs, consider the MSS1278 as an alternative to this series. The MSS1278 series is more cost effective, features a smaller footprint, lower DCR and better current handling. We will continue to manufacture and support the DS5022P indefinitely. 1 Part Number DS5022P-102ML_ DS5022P-222ML_ DS5022P-332ML_ DS5022P-472ML_ DS5022P-562ML_ DS5022P-103ML_ DS5022P-153ML_ DS5022P-223ML_ DS5022P-333ML_ DS5022P-473ML_ DS5022P-683ML_ DS5022P-104ML_ DS5022P-154ML_ DS5022P-224ML_ DS5022P-274ML_ DS5022P-334ML_ DS5022P-474ML_ DS5022P-684ML_ DS5022P-824ML_ DS5022P-105ML_ L DCR ±20%2 max (µH) (Ohms) 1.0 0.016 2.2 0.023 3.3 0.026 4.7 0.028 5.6 0.030 10 0.040 15 0.048 22 0.059 33 0.075 47 0.097 68 0.138 100 0.207 150 0.293 220 0.47 270 0.64 330 0.78 470 1.08 680 1.40 820 1.70 1000 2.01 SRF typ (MHz) 130 70 60 40 33 30 20 18 14 10 9.0 7.0 6.0 5.0 4.5 4.0 3.0 2.5 2.2 2.0 Isat3 (A) 18.0 14.0 12.5 11.5 10.8 8.0 7.0 6.0 5.0 4.0 3.0 2.4 2.1 1.9 1.4 1.1 1.1 0.96 0.88 0.80 Irms4 (A) 6.5 5.0 4.7 4.4 4.1 3.9 3.4 3.1 2.8 2.4 2.0 1.7 1.3 1.1 0.95 0.86 0.73 0.64 0.58 0.53 1. When ordering, please specify termination and packaging codes: DS5022P-105MLD Termination: L = RoHS compliant gold over nickel over phos bronze. Special order: T = RoHS tin-silver-copper (95.5/4/0.5) or S = non-RoHS tin-lead (63/37). Packaging: D = 13″ machine-ready reel. EIA-481 embossed plastic tape (250 parts per full reel). B = Less than full reel. In tape, but not machine ready. To have a leader and trailer added ($25 charge), use code letter D instead. 2. Inductance tested at 0.1 Vrms, 100 kHz, 0 Adc. 3. DC current at which the inductance drops 10% (typ) from its value without current. 4. Current that causes a 40°C temperature rise from 25°C ambient. 5. Ambient temperature range: –40°C to +85°C with Irms current +85°C to +125°C with derated current 6. Storage temperature range: Component: –40°C to +125°C Packaging: –40°C to +80°C 7. Resistance to soldering heat: Three reflows at >217°C for 90 seconds (+260°C ±5°C for 20 – 40 seconds), allowing parts to cool to room temperature between. 8. Electrical specifications at 25°C.
