For DC-DC converters  
and other applications  
Coupled Inductors–LPR4012  
The LPR4012 miniature shielded coupled inductors are  
only 1,1 mm high and 4 mm square. The excellent  
coupling coefficient (k = 0.95) makes them ideal for use  
as flyback transformers in DC-DC converters or as  
coupled inductors in buck regulators to provide multiple  
outputs. The wide selection of turns ratios makes them  
suitable for a variety of voltage step-up and step-down  
applications. They can also be used in autotransformer  
applications.  
The high Isat and low DCR ratings of these low profile  
parts provide high efficiency and excellent current han-  
dling in a rugged, low cost design.  
Custom inductance values and turn ratios are available  
upon request.

1. Please specify termination and packaging codes:  
LPR4012-223XMLC  
Termination: L = RoHS compliant Silver-palladium-platinum-glass frit.  
Special order: T = RoHS tin-silver-copper (95.5/4/0.5) or  
S = non-RoHS tin-lead (63/37).  
Packaging: C = 7″ machine-ready reel. EIA-481 embossed plastic tape (1000 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 (3500 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. When leads are connected in parallel, SRF is the same value.  
4. DC current applied to L1, at which the inductance drops the specified amount from its value without current.  
5. Current applied to L1 that causes the specified temperature rise from 25°C ambient.  
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.  
Specifications subject to change without notice.
