1 Inductance measured at 100 kHz, 0.1 V, 0 Adc using an Agilent/HP 4263B impedance analyzer or equivalent.
2 DCR measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
3 SRF tested on an Agilent/HP 4192A.
4 Isat: DC current at 25°C that causes the specified inductance drop from its value without current.
5 Irms: Current that causes the specified temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings.
6 Ambient temperature range: −40°C to +85°C with (40°C) Irms current.
7 Storage temperature range: Component: −40°C to +85°C
Packaging trays: −40°C to +80°C
8 Maximum part temperature: +125°C (Ambient + temperature rise)
9 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.
