Power Transformer ForMaxim MAX5074
Isolated PWM Power IC
The C0984-CL transformer is designed specifically for the
Maxim MAX5074 isolated PWM power IC in a forward DC-
DC converter. It can be used in power supplies for IEEE
802.3af-compliant PoE applications, IP phones, WLAN
Access-Points and a variety of other telecom applications
with an input voltage range from 36 V to 72 V.
This transformer features very low secondary winding
DCR and 1500 Vrms isolation from the primary and bias
windings to the secondary.
Coilcraft can also custom engineer a transformer to meet
your specific requirements. For free evaluation samples,

1. When ordering, please specify a packaging code:
Packaging:
C0984-CLD
D = 13″ machine ready reel. EIA-481 embossed plastic
tape (200 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 10 kHz, 0.1 Vrms, 0 Adc.
3. Leakage inductance is for the primary winding with the other windings
shorted.
4. Operating temperature range –40°C to +125°C.
5. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
