Document 290 -1 SMT Power Inductors - SER1360 Series The SER1360 series provides exceptionally high current carrying capability (up to 43 Amps) and very low DC resistance, all in a low profile, small footprint package. The part’s magnetic shielding and 13 × 13 mm base allow high density mounting while the flat wire winding keeps the overall height to just 6 mm. In addition to the standard values show, custom values are available to meet specific applications.

When ordering, please specify termination and packaging codes: SER1360-103KLD Termination: L = RoHS compliant matte-tin 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 (500 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 measured at 100 kHz, 0.1 Vrms, 0 Adc on an Agilent/ HP 4284A or equivalent. 3. DCR measured on a micro-ohmmeter. 4. SRF measured using an Agilent/HP 8753D network analyzer and a Coilcraft SMD-D test fixture. 5. DC current at which the inductance drops 10% (typ) from its value without current. 6. Current that causes a 40°C temperature rise from 25°C ambient. 7. Electrical specifications at 25°C. Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
