1 Inductance tested at 10 kHz, 0.1 Vrms, 0 Adc using an Agilent/HP 4132 impedance analyzer or equivalent.
2 DCR at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
3 Isat: DC current at 25°C that causes a 10% (typ) inductance drop from its value without current.
Temperature derating curves.
4 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. Temperature derating curves.
5 Ambient temperature range: −40°C to +125°C with (40°C rise) Irms Derating curves
6 Storage temperature range: Component: −40°C to +165°C
Packaging trays: −40°C to +80°C
7 Maximum part temperature: +165°C (Ambient + temperature rise)
8 Resistance to soldering heat: Three reflows at >217°C for 90 seconds (+260°C ±5°C for 20 – 40 seconds), allowing parts to cool to room temperature between.
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.
