Coupled Inductors –
LPR6235
For Step-Up, Resonant
& Flyback Applications
• Can be used as step-up or flyback transformers in DC-DC
converters or as autotransformers
• Perfect for low voltage step-up in energy harvesting applications
• Selected by Linear Technology for the LTC3108 and LTC3109
Ultralow Voltage Step-Up Converter and Power Managers
These shielded parts are only 3.5 mm high and 6 mm
square. The excellent coupling coefficient (k = 0.95)
makes them ideal for use in a variety of applications.
They can be used as flyback transformers and step-up
pulse transformers.
The high Isat and low DCR ratings of these parts provide
high efficiency and excellent current handling in a rug-
ged, low cost design.
Custom inductance values and turn ratios may be avail-
able upon request.

1. When ordering, please specify packaging code:
LPR6235-253PMLC
Packaging: C = 7″ machine-ready reel. EIA-481 embossed plastic tape
(350 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.
D = 13″ machine-ready reel. EIA-481 embossed plastic
tape. Factory order only, not stocked (1500 parts per full
reel).
2. Inductance is measured at 100 kHz, 0.1 Vrms, 0 Adc on an Agilent/HP
4284A LCR meter or equivalent.
3. SRF measured using an Agilent/HP 4191A or equivalent.
4. DC current applied to L1, at which the inductance drops 10% from its value
without current.
5. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
