1. When ordering, please specify termination and testing codes:
ST450PHD473MLZ
Termination: L = Silver-palladium-platinum-glass frit terminations
Special order:
T = RoHS tin-silver-copper (95.5/4/0.5) or
S = non-RoHS tin-lead (63/37).
Testing: Z = COTS
H = Screening per Coilcraft CP-SA-10001
2. Per winding. Tested at 100 kHz, 0.1 Vrms, 0 Adc.
3. Q measured at 1 MHz.
4. DC current at which the inductance drops 10% (typ) from its value
without current.
5. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
