encapsulatedtelecommunicationsferrite core

• Designed for forward topology operating at 250 kHz • Five outputs from 3.3 V to 15 V; 18 - 36 V input • 1500 Vrms isolation from primary and aux to the secondary • pecified by Texas Instruments for its LM5015 Two-Switch Forward Regulator Core material Ferrite Terminations RoHS tin-silver over tin over nickel over phos bronze. Other terminations available at additional cost. Weight 4.0-4.3 g Ambient température -40°C to +85°C Storage température Component: -40°C to +85°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, 0.3 Vrms, 0 Adc. 2. DCR for the secondary is measured with the windings connected in parallel. 3. Leakage inductance is for the primary and is measured with the secondary shorted. 4. Turns ratio is with the secondary windings connected in parallel. 5. Output is with the secondary windings connected in parallel. Auxiliary winding output is 10 V, 20 mA. 6. Electrical spécifications at 25°C. 7.
