1. When ordering, please specify termination and testing codes:
ST511PNA104MLZ
Termination: L = RoHS compliant gold over nickel over phos bronze.
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. Inductance tested at 100 kHz, 0.1 Vrms, 0 Adc using an Agilent/
HP 4263B LCR meter or equivalent.
3. SRF measured using Agilent/HP 4191A or equilvalent.
4. DC current at which the inductance drops the specified amount from
its value without current.
5. Current that causes the specified temperature rise from 25°C ambient.
6. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
