• Flyback and Forward transformers for PoE up to 72 Watts
• Operates with 9 – 57 V input (POE21, 22, 24, 33, 35 and 38)
• Operates with 33 – 57 V input (POE23, 30, 36, 53, 70, and 72)
• One minute isolation (hipot): 1500Vrms, from pri and aux to each
sec; 500Vrms from pri to aux; 500Vrms between two secondary
• Dual outputs can be configured as one single higher power output
• AEC-Q200 Grade 1 (–40°C to +125°C)

Core material Ferrite

Environment RoHS compliant, halogen free

Terminations Tin-silver-copper over tin over nickel over phos bronze

Weight 7.1 – 7.9 g

Ambient temperature –40°C to +125°C

Maximum part temperature +165°C (Ambient + temp rise)

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 200 kHz, 0.1 Vrms, 0 Adc.
3. Leakage inductance measured between pins 1 and 3 with all other
pins shorted.
4. Output is for each secondary. Output of the aux winding is 10 V, 50 mA.
5. Based on 280 mT at 25°C and number of turns on pins 1-3.
6. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
