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.

1. When ordering, please specify
packaging
code:
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: –40°C to +85°C.
Electrical specifications at 25°C.
