LPR4012 & Flyback Applications  
Coupled Inductors  
–
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 handling  
in a rugged, low cost design.  
Custom inductance values and turn ratios are available  
upon request.

1. When ordering, please specify termination and packaging codes:  
LPR421ꢀ-ꢀꢀ3XMRC  
Termination: R = RoHS compliant matte tin over nickel over silver.  
Special order: Q = RoHS tin-silver-copper (95.5/4/0.5) or  
P = 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 at 25°C applied to L1 that causes the specified inductance drop from its value without current.  
5. Current applied to L1 that causes the specified temperature rise from 25°C ambient.This information is for reference only and does not represent absolute  
maximum ratings.  
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
