Isolation transformer YCEFD series

encapsulatedtelecommunicationsferrite core

• Designed to meet 30 W PoE IEEE 802.3at-2009 standard. Opérâtes at 250 kHz with 36-72 Volts input. • 1500 Vrms, one minute isolation, primary and bias to secondary • Bias winding output: 12 V; sync winding output: 5 V Core material Ferrite Terminations RoHS tin-silver over tin over nickel over phos bronze. Other terminations available at additional cost. Weight 10.1 -10.7 g Ambient température -40°C to +125°C Storage température Component: -40°C to +125°C. Tape and reel packaging: -40°C to +80°C Résistance to soldering heat Max three 40 second reflows at +260°C, parts cooled to room température between cycles Moisture Sensitivity Level (MSL) 1 (unlimited floor life at <30°C / 85% relative humidity) 1. Inductance is measured at 250 kHz, 0.2 Vrms, 0 Adc. 2. DCR for the primary and secondary is with the windings connected in parallel. 3. Leakage inductance is for the primary windings with the secondary windings shorted. 4. Turns ratio is with the primary windings and the secondary windings connected in parallel. 5. These inductors are recommended for 30% ripple current. Ripple less than 30% may require the use of physically larger inductors. Allowing higher ripple current to make use of smaller inductors may create a risk of discontinuous output current. 6. Operating température range -40°C to +125°C. 7. Electrical spécifications at 25°C. Refer to Doc 362 “Soldering Surface Mount Components" before soldering.
