Document 703-1 E R U T A R E P M HIGH TE Shielded Coupled Inductors MSD1260T The MSD1260T series of shielded coupled inductors was designed specifically for high temperature applications - up to 125C ambient. Tight coupling (k 0.97) and 500 Vrms isolation make them ideal for use in a variety of circuits including flyback, multioutput buck, SEPIC and Zeta. These parts provide high inductance, high efficiency and excellent current handling. They can also be used as two single inductors connected in series or parallel or as a common mode choke. + + D L1 C L2 VOUT C VIN - SW - Typical Flyback Converter 0.484 max 12,3 0.484 max 12,3 123 X D L2 + VOUT C AUX - + Dot indicates pin1 Dash number + VIN L1 D SW VOUT C - Internal code - Typical Buck Converter with auxiliary output 0.236 0.008* 6,0 0,2 Recommended Land Pattern 0.217 5,5 0.197 5,0 0.138 3,5 0.197 5,0 D + 4 2 1 2 1 3 4 VIN C 0.177 4,5 VIN 0.079 2,0 - Dimensions are in inches mm 1 L1 3 C 2 VOUT - + * For optional tin-lead and tin-silver-copper terminations, dimensions are for the mounted part.

When ordering, please specify termination and packaging codes: Coupled Inductor Core and Winding Loss Calculator MSD1260T-105KLD 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 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 which the inductance drops the specified amount 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. 8. Maximum current when applied to one winding that causes a 40C temperature rise from 25C ambient. 9. Electrical specifications at 25C.
