1 Inductance measured at 500 kHz, 0.1 Vrms, 0 Adc on an Agilent/HP 4284A LCR meter or equivalent
2 DCR measuredat 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 4395A network analyzer and an Agilent/HP 16193A test fixture.
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 +125°C
Tape and reel packaging: −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.
