LPR4012 Series

Coupled Inductors for Step-Up & Flyback Applications

This is a new halogen free version recommended for new designs. Only the termination material and part number have changed. The previous version is available only to current customers.

Coilcraft LPR4012 Series low-profile 1:N coupled power inductors are ideal for a variety of voltage step-up and step-down applications, including low voltage step-up in energy harvesting designs. They offer excellent coupling coefficient (K > 0.95) and 100 Vrms, one-minute isolation (hipot) between windings.

Perfect for low voltage step-up in energy harvesting applications
Different turns ratios for a variety of voltage step-up and step-down applications.
Coupled, low profile shielded power inductor – only 1,1 mm high, 4 mm square
Uses: flyback transformers in DC-DC converters; coupled inductors in buck regulators to provide multiple outputs; autotransformers

Hinweise

When ordering, please specify termination and packaging codes: e.g. LPR4012-223DMRC
Inductance is measured at 100 kHz, 0.1 Vrms, 0 Adc on an Agilent/HP 4284A LCR meter or equivalent.
DCR at 25°C. For other operating temperatures, use this DCR at Temperature calculator
SRF measured using an Agilent/HP 4191A or equivalent. When leads are connected in parallel, SRF is the same value.
Isat: DC current applied to L1 at which the inductance drops the specified amount from its value without current.
Irms: 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. Determine temperature rise.

Anschlüsse:

R = Matte tin over nickel over silver.
Q = RoHS tin-silver-copper (95.5/4/0.5). (Special order, added cost)
P = non-RoHS tin-lead (63/37). (Special order, added cost)

Verpackung:

C = 7″ machine-ready reel. EIA-481 embossed plastic tape (1000 parts per full reel). Quantities less than full reel available: in tape (not machine ready) or with leader and trailer ($25 charge).
D = 13″ machine-ready reel. EIA-481 embossed plastic tape. Factory order only, not stocked (3500 parts per full reel).
B = Less than full reel. In an effort to simplify our part numbering system, Coilcraft is eliminating the need for multiple packaging codes. When ordering, simply change the last letter of your part number from B to C.
