Document 187-1 SMT Power Inductors – DS3316P Magnetic shielding and high efficiency are features of the DS3316 family of power inductors. They are designed for high performance DC-DC converter applications, especially those requiring shielding. The terminations wrap around the end of the base, ensuring a sound solder fillet and simplifying inspection. Saturation current ratings up to 11 A and rms current ratings as high as 5 A are available. DC resistance as low as 0.021 Ohms keeps power losses to a minimum. For new designs, consider the MSS1038 as an alternative to this series. The MSS1038 series is more cost effective, features a smaller footprint, lower profile, lower DCR and better current handling. We will continue to manufacture and support the DS3316 indefinitely.

When ordering, please specify termination and packaging codes: DS3316P-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 (1000 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. See Qualification Standards section for environmental and test data. Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
