Document 417-1 SMT Planar Transformers For Applications up to 140 Watts The PL140 surface mount planar transformers are rated for 140 Watts and are designed to operate between 200 kHz and 500 kHz. 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.

When ordering, please specify packaging code: 2. 3. 4. 5. PL140-114LD 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. To order a transformer with an optional auxiliary winding, add an "X" and the turn count after the PL140, e.g. PL140X3-100LB. Turn counts of 2, 3, 4, 5, 7 and 9 are available for the auxiliary winding. Transformers with auxiliary windings are not stocked. 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.
