1 Inductance tested at 300 kHz, 0.1 Vrms, using an Agilent/HP 4192A or equivalent.
2 DCR measured at 25°C on a Keithley 580 micro-ohmmeter or equivalent. For other operating temperatures, use this DCR at Temperature calculator.
3 SRF measured using an Agilent/HP 8753ES network analyzer or equivalent.
4 Isat: DC current at 25°C that causes the specified inductance drop from its value without current.
Temperature derating curves.
5 Irms: Current that causes the specified temperature rise from 25°C ambient. Temperature rise of the core is usually less than that of the winding. This information is for reference only and does not represent absolute maximum ratings. Temperature derating curves.
6 Ambient temperature range: −40°C to +85°C with Irms current.
7 Storage temperature range: Component:−40°C to +125°C
Packaging trays:−40°C to +80°C
8 Maximum part temperature: +125°C (Ambient + temperature rise)
7 Electrical specifications at 25°C.
Refer to Soldering Coilcraft Components before soldering.
PCB washing: Tested to MIL-STD-202 Method 215 plus an additional aqueous wash. More info.
