They are available in 15 turns ratios and six different schematics, and may be special ordered with an auxiliary winding. These transformers are ideal for use in high-current power supply applications such as open loop intermediate bus converters (IBC) and closed loop voltage mode converters. They are designed for use with nominal -48 V input. Output voltages depend on the turns ratio, duty cycle and circuit topology. They offer high efficiency and feature excellent DCR, very low leakage inductance and 1500 Vdc primary to secondary isolation. Coilcraft can custom design planar transformers with different turns ratios to meet your specific requirements. Coilcraft Designer's Kit C390 contains two samples each of the parts shown in bold. To order, contact Coilcraft, or visit http://order.coilcraft.com to purchase on-line.

When ordering, please specify termination and packaging codes: PL140-114LD Termination: L = RoHS compliant matte tin over nickel over brass. 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 (200 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. Inductance measured on an Agilent/HP 4284 between pins 2 and 4 at 200 kHz, 0.1 Vrms, 0 Adc. Leakage inductance measured between pins 2 and 4 at 100 kHz, 0.1 Vrms, 0 Adc with all secondary pins shorted. Storage and ambient operating temperature range: -40C to +85C. Electrical specifications at 25C.
