For Applications  
up to 140 Watts  
SMT Planar Transformers  
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.  
Thesetransformersareidealforuseinhigh-currentpower  
supply applications such as open loop intermediate bus  
converters(IBC)andclosedloopvoltagemodeconverters.  
Theyaredesignedforusewithnominal−48Vinput.Output  
voltages depend on the turns ratio, duty cycle and circuit  
topology.They offer high efficiency and feature excellent  
DCR,verylowleakageinductanceand1500Vdcprimary  
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.

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.  
2. Inductance measured on an Agilent/HP 4284 between pins 2 and 4 at 200 kHz, 0.1 Vrms, 0 Adc.  
3. Leakage inductance measured between pins 2 and 4 at 100 kHz, 0.1 Vrms, 0 Adc with all secondary pins shorted.  
4. Storage and ambient operating temperature range: –40°C to +85°C.
