POE51Q-48ED Power Transformers IEEE802.3bt Standard And Operates With 36 – 57 V Input

• 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)

Storage temperature Component: –40°C to +165°C

Tape and reel packaging: –40°C to +80°C

Resistance to soldering heat Max three 40 second reflows at +260°C, parts cooled to room temperature between cycles

Moisture Sensitivity Level (MSL) 1 (unlimited floor life at <30°C / 85% relative humidity)

Failures in Time (FIT) / Mean Time Between Failures (MTBF)

38 per billion hours / 26,315,789 hours, calculated per Telcordia SR-332

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.
