When ordering, please specify termination and testing codes: ST458RFW04C1LZ Termination: L = Tin-silver-copper (95.5/4/0.5) over silver palladium-platinum-glass frit. Special order: S = Tin-lead (63/37). Testing: Z = COTS H = Screening per Coilcraft CP-SA-10001 2. Impedance ratio is for the full primary winding to the full secondary winding. 3. Inductance measured at 100 kHz, 0.1 V, 0 Adc on an Agilent/HP 4192 or equivalent. 4. DCR measured on a micro-ohmmeter. 5. DC imbalance is the maximum difference in current measured at pins 4 and 6 with the source at pin 5. Inductance drop is 15% at maximum imbalance. 6. Electrical specifications at 25°C. Measurements are referenced to 50 Ohms. Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
