1	When ordering, please specify termination and packaging codes: e.g. XAL5050-223MEC
	Termination:	E = Halogen free component. RoHS compliant tin-silver over copper terminations. Special order, added cost: T = RoHS tin-silver-copper (95.5/4/0.5) or S = non-RoHS tin-lead (63/37).
	Packaging:	C = 7" machine-ready reel EIA-481 embossed plastic tape (XAL5030: 400 parts per full reel; XAL5050: 250 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. D = 13" machine-ready reel EIA-481 embossed plastic tape. Factory order only, not stocked (XAL5030: 1500 parts per full reel; XAL5050: 750 parts per full reel).

2	Inductance tested at 100 kHz, 0.1 Vrms, 0 Adc.
3	DCR measured at 25°C on a micro-ohmmeter. For other operating temperatures, use this DCR at Temperature calculator.
4	SRF measured using an Agilent/HP 4395A or equivalent.
5	Isat: DC current at which the inductance drops 30% (typ) from its value without current. Details
6	Irms: Current that causes the specified temperature rise from 25°C ambient. Irms testing was performed on 0.75 inch wide × 0.25 inch thick copper traces in still air. Temperature rise is highly dependent on many factors including pcb land pattern, trace size, and proximity to other components. Therefore temperature rise should be verified in application conditions.
7	Ambient temperature range:	–40°C to +125°C with Irms current. +125°C to +165°C with derated current. Derating curve
8	Storage temperature range:	Component: –40°C to +165°C Tape and reel packaging: –40°C to +80°C
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 with pure water or alcohol only. Other solvents.
