1 Inductance tested at 100 kHz, 0.1 Vrms, 0 Adc on an Agilent/HP 4263B LCR meter or equivalent.
2 DCR at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
3 SRF measured using an Agilent/HP 4191A or equivalent. Details
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. 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 (40°C rise) Irms Derating curves
7 Storage temperature range: Component: −40°C to +125°C
Packaging trays or tape: −40°C to +80°C
8 Maximum part temperature: +125°C (Ambient + temperature rise)
9 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.
10 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.
