1. Inductance tested at 300 kHz, 0.1 Vrms on Agilent/HP 4192A.
2. DCR measured on a Keithley 580 micro-ohmmeter or equivalent.
3. SRF measured on an Agilent/HP 8753ES network analyzer.
Caution:
This series is not intended for use
4. DC current at 25°C that causes the specified inductance drop from its value without current.
Click for temperature derating information.
5. Current that causes the specified temperature rise from 25°C ambient. This information is
for reference only and does not represent absolute maximum ratings.
Click for temperature derating information.
Temperature rise of the core is usually less than that of the winding.
When Irms is greater than Isat, Isat is the more critical specification and Irms is shown in
gray type.
in high vibration environments. We
advise using additional means of
securing the part to the circuit board
to ensure its adhesion.
6. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
