product
1. To order a transformer with an optional auxiliary winding, add an “X” and the turn count after the PL300, e.g. PL300X3-100L.
Turn counts of 2, 3, 4, 5, 7 and 9 are available for the auxiliary winding. Transformers with auxiliary windings are not stocked.
2. Inductance measured on an Agilent/HP 4284 at 200 kHz, 0.5 Vrms, 0 Adc between pins 2 and 5 with pins 3 and 4 connected.
3. Leakage inductance measured at 200 kHz, 0.5 Vrms, 0 Adc between pins 2 and 5, with pins 3 and 4 connected, and with all
secondary pins shorted.
4. DCR for secondary is measured between pins 7 and 11.
5. Volt-time product is based on primary windings connected in series.
6. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
