code:
MS598PTA103KSZ
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 10% (typ) from its value without current.
6. Typical current that causes a 40°C temperature rise from 25°C ambient.
7. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
