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:

LPR6235-253PMRC

Packaging: C

= 7″ machine-ready reel. EIA-481 embossed plastic tape

(350 parts per full reel).

= Less than full reel. In tape, but not machine ready. To

have a leader and trailer added ($25 charge), use code

letter D instead.

= 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.
