Power Transformer ForMaximMAX5074
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
11 V to 76 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

1. When ordering, please specify a packaging code:
C0984-CLD
Packaging: 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.
