For ST Microelectronics
STE12PS PSE Power Controller
1. When ordering, please specify a packaging code:
DA2420-AL
D
Packaging: D =13
″ machine ready reel. EIA-481 embossed plastic
tape (175 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.
These surface mount flyback transformers were devel-
oped specifically for the ST Microelectronics STE12PS
12-Channel PSE Power Control Device.
They are designed to work with a 3.3 V input to provide
a 12 V output. Isolation is 500 Vdc from each primary
winding to the secondary winding.
Coilcraft can also design custom transformers with
voltage, inductance and DCR values to meet your
specific requirements.
For free evaluation samples, contact Coilcraft or order
them on-line at www.coilcraft.com.
2. Inductance is for the primary, measured at 100 kHz, 0.1 Vrms, 0 Adc.
3.
Ipk is the peak current drawn at minimum input voltage.
4. Leakage inductance measured on the primary windings with all
secondary pins shorted.
5. Turns ratio is with the primary windings connected in parallel.
6. Operating temperature range –40°C to +125°C.
7. Electrical specifications at 25°C.
Weight:
14.1 – 14.6 g
Terminations:
Tin-silver over tin over nickel over phos bronze
Tape and reel:
175/13
″ reel, 44 mm tape width
