1. 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.
