When ordering, please specify testing code: ML558PTA572MLZ Testing: Z = COTS H = Group A screening per Coilcraft CP-SA-10001 N = Group A screening per Coilcraft CP-SA-10004 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 25C ambient. 7. Electrical specifications at 25C. Refer to Doc 362 "Soldering Surface Mount Components" before soldering.
