LPR6235 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 LPR6235 Series low-profile 1:N shielded 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 300 Vrms, one-minute isolation (hipot) between windings.

Different turns ratios for a variety of voltage step-up and step-down applications.
Perfect for low voltage step-up in energy harvesting applications
Selected by Linear Technology for their LTC3108 and LTC3109 Ultralow Voltage Step-Up Converter and Power Managers
Excellent coupling coefficient: K > 0.95

注释

When ordering, please specify termination and packaging codes: e.g. LPR6235-253PMRC
Inductance is measured at 100 kHz, 0.1 Vrms, 0 Adc for -253LMR. All other values are measured at 10 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.
Isat: DC current applied to L1 at which the inductance drops 10% from its value without current.

端子:

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)

包装:

C = 7″ machine-ready reel. EIA-481 embossed plastic tape (350 parts per full reel). Quantities less than full reel available: in tape (not machine ready) or with leader and trailer ($25 charge).
B = 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.
D = 13″ machine-ready reel. EIA-481 embossed plastic tape. Factory order only, not stocked (1500 parts per full reel).
