1 When ordering, please specify termination and packaging codes: e.g. WA8514-AEC


C = 7" machine-ready reel
EIA-481 embossed plastic tape (2000 parts per full reel).
B = Less than full reel
In tape, but not machine-ready. To have a leader and trailer added ($25 charge), use code letter C instead.
2 Inductance tested at 100 kHz, 0.1 Vrms, 0 Adc using an Agilent/HP 4284A impedance analyzer.
3 DCR measured at 25°C on a micro-ohmmeter. For other operating temperature use this DCR at Temperature calculator.
4 Isat: DC current at 25°C that causes an inductance drop of 30% (typ) 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 +125°C with (20°C rise) Irms Derating curves
7 Storage temperature range: Component: −40°C to +145°C
Tape and reel packaging: −40°C to +80°C
8 Maximum part temperature: +155°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.
