Please specify termination and packaging codes: Coupled Inductor Core and Winding Loss Calculator This web-based utility allows you to enter frequency, peak-to-peak LPD4012-334MRC (ripple) current, and Irms current to predict temperature rise and Termination: R = RoHS compliant, matte tin over nickel over silver. overall losses, including core loss. Go to online calculator. Special order: Q = RoHS tin-silver-copper (95.5/4/0.5) or P = non-RoHS tin-lead (63/37). Packaging: C = 7 machine-ready reel. EIA-481 embossed plastic tape (1000 parts per full reel). Quantities less than full reel available: in tape (not machine ready) or with leader and trailer ( 25 charge). B = Less than full reel. In an effort to simplify our part numbering system, Coilcraft is eliminating the need for multiple packaging codes. When ordering, simply change the last letter of your part number from B to C. D = 13 machine-ready reel. EIA-481 embossed plastic tape. Factory order only, not stocked (3500 parts per full reel). 2. Inductance shown for each winding, measured at 100 kHz, 0.1 Vrms, 0 Adc on an Agilent/HP 4284A LCR meter or equivalent. When leads are connected in parallel, inductance is the same value. When leads are connected in series, inductance is four times the value. 3. DCR is for each winding. When leads are connected in parallel, DCR is half the value. When leads are connected in series, DCR is twice the value. 4. SRF measured using an Agilent/HP 4191A or equivalent. When leads are connected in parallel, SRF is the same value. 5. Leakage Inductance is for L1 and is measured with L2 shorted. 6. DC current at 25C that causes the specified inductance drop from its value without current. It is the sum of the current flowing in both windings. 7. Equal current when applied to each winding simultaneously that causes a 40C temperature rise from 25C ambient. This information is for reference only and does not represent absolute maximum ratings. 8. Maximum current when applied to one winding that causes a 40C temperature rise from 25C ambient. This information is for reference only and does not represent absolute maximum ratings. 9. Electrical specifications at 25C. Refer to Doc 639 Selecting Coupled Inductors for SEPIC Applications. Refer to Doc 362 Soldering Surface Mount Components before soldering.
