2	Inductance tested at 130 kHz, 0.1 Vrms, 0 Adc.
3	DCR at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
4	Ambient temperature range:	–40°C to +85°C
5	Storage temperature range:	Component: –40°C to +85°C Tape and reel packaging: –40°C to +80°C
6	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.
7	Electrical specifications at 25°C. Measurements are referenced to 50 Ohms.
Refer to Soldering Coilcraft Components before soldering.
PCB washing: Tested with pure water or alcohol only. Other solvents
