GA3250-BE Coupled Power Inductor

for Maxim MAX14521E

The GA3250-BE and GA3250-BL will no longer be available for purchase after 10/02/21. Please see the GA3250-EE, which is a drop-in replacement that provides a more robust design. The upgraded part offers the same electrical performance, 1:8 turns ratio and has the same dimensions that fit the same land pattern.

Developed for Maxim MAX14521E High-Voltage EL Lamp Driver with I²C Interface
Used as a 1 : 8 autotransformer
Shielded part for high-density applications
Miniature, low profile part – only 3 x 3 x 1 mm
RoHS-compliant, halogen free. 260°C compatible. Silver-palladium-platinum-glass frit terminations
COTS Plus tin-silver-copper and tin-lead terminations available

Hinweise

When ordering, please specify termination and packaging code: e.g. GA3250-BLC
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.
Isat: DC current at which the inductance of L1 drops 20% from its value without current.
Current applied to both winding in parallel that causes a 40°C temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings.

Anschlüsse:

E = Silver-palladium-platinum-glass frit terminations.
T = RoHS tin-silver-copper (95.5/4/0.5). (Special order, added cost)
S = 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). Quantities less than full reel available: in tape (not machine ready) or with leader and trailer ($25 charge).
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 D.
