When ordering, please specify packaging code: DA2034-ALD Packaging: 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). B = Less than full reel. In tape, but not machine ready. To have a leader and trailer added ($25 charge), use code letter D instead. 2. Inductance is for the primary, measured at 100 kHz, 0.1 Vrms, 0 Adc. 3. Peak primary current drawn at minimum input voltage. 4. DCR is with the primary windings connected in parallel. 5. Leakage inductance is with the primary windings connected in parallel and with the secondary winding shorted. 6. Capacitance measured at 100 kHz, 0.1 Vrms from pin 3 to pin 1 with all other pins shorted. 7. Electrical specifications at 25°C.

DA2033-AL and DA2034-AL are also specified for the LT3751 Controller. They have a smaller footprint than other transformers designed for this application. These low-profile transformers feature 1500 Vrms, one minute winding to winding isolation and 750 Vrms winding to core isolation. They are designed to operate with an input range of 3 – 24 V and to charge a capacitor to 300 V. They are shown on the Linear Technology LT3750 ap - plication 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). Coilcraft can also custom engineer a transformer to meet your specific requirements. For free evaluation samples, contact Coilcraft or visit www.coilcraft.com.
