SMT Planar Transformers ForApplications
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. To order, contact Coilcraft,

1. 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.
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.
5. Electrical specifications at 25°C.
