• Developed for Flyback DC/DC PoE PD power converters up to 51 W
• Designed to meet the upcoming IEEE802.3bt standard and operates with 36 – 57 V input
• 1500 Vrms, one minute isolation (hipot) between primary and auxiliary to secondary.
• Perfect solution for high power PoE applications including Smart Building and IoT
• AEC-Q200 Grade 1 (–40°C to +125°C)
1. Packaging: D = 13″ machine-ready reel. EIA-481 embossed plastic tape (150 parts per full reel).
Quantities less than full reel available: in tape (not machine ready) or with leader and trailer ($25 charge).
2. Inductance is for the primary, measured at 250 kHz, 0.5 Vrms, 0 Adc.
3. Leakage inductance is for the primary with the secondary and aux windings shorted.
4. DC current at 25°C that causes an inductance drop of <15% (POExx51Q) and <15% (POExx40Q) from its value without current.
5. Output is for the secondary. Output of the aux winding is 12 V, 30 mA.
6. Electrical specifications at 25°C. Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
