1. When ordering, please specify testing code:
ML558PTA572MLZ
Testing: Z = COTS
H= Screening per Coilcraft CP-SA-10001
N= Screening per Coilcraft CP-SA-10004
C= Custom screening (please specify when ordering)
2. Inductance measured at 100 kHz, 0.1 Vrms, 0 Adc on an Agilent/HP 4284A or equivalent.
3. DCR measured on a micro-ohmmeter.
4. SRF measured using an Agilent/HP 8753D network analyzer.
5. Typical DC current at which the inductance drops the specified amount from its value without current.
6. Typical current that causes the specified temperature rise from 25°C ambient.
7. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
