Shielded Coupled Inductor for
Maxim MAX14521E

GA3250-BE is the new part number. The previous part number GA3250-BL is no longer available. The parts are the same, only the part number has changed.
  • 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 4 mm square and 1,1 mm high
  • RoHS-compliant, halogen free. 260°C compatible. Silver-palladium-platinum-glass frit terminations
  • COTS Plus tin-silver-copper and tin-lead terminations available

1 When ordering, please specify termination and packaging code: e.g. GA3250-BLC
  Termination: E = Silver-palladium-platinum-glass frit terminations.
Special order, added cost: T = RoHS tin-silver-copper (95.5/4/0.5) or
S = non-RoHS tin-lead (63/37).


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 C 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 DCR at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
4 Isat: DC current at which the inductance of L1 drops 20% from its value without current.
5 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.
6 Ambient temperature range: −40°C to +85°C
7 Storage temperature range: Component: −40°C to +125°C
Tape and reel packaging: −40°C to +80°C
8 Resistance to soldering heat: Three reflows at >217°C for 90 seconds (+260°C ±5°C for 20 – 40 seconds), allowing parts to cool to room temperature between.
9 Electrical specifications at 25°C.
Refer to Soldering Coilcraft Components before soldering.
PCB washing: Tested to MIL-STD-202 Method 215 plus an additional aqueous wash. More info.
