Flyback Transformers

for Linear Technology LT3750 / LT3751

Designed for use with Linear Technology LT3750 Capacitor Charger Controller
Smaller footprint than other transformers for this application
For charging capacitors to 300 V
Shown on LT3750 application note for use in a 300 V, 3 A charging circuit (DA2032); a 300 V, 6 A charging circuit (DA2033); and a 300 V, 9 A charging circuit (DA2034)
DA2033-AL and DA2034-AL are also specified for the LT3751 Controller.

注释

When ordering, please specify packaging code: e.g. DA2034-ALD
Inductance is for the primary, measured at 100 kHz, 0.1 Vrms, 0 Adc.
DCR is at 25°C with the primary windings connected in parallel. For other operating temperatures, use this DCR at Temperature calculator.
Leakage inductance is with the primary windings connected in parallel and with the secondary winding shorted.
1500 Vrms primary to secondary isolation and 750 Vrms winding to core isolation, tested for one minute.

端子:

RoHS compliant tin-silver over tin over nickel over phos bronze. Other terminations available at additional cost.

包装:

D = 13″ machine-ready reel. EIA-481 embossed plastic tape (DA2032-AL & DA2033-AL: 200 parts per full reel; DA2034-AL: 175 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.
