* L2 when used with LM258X Series of SIMPLE SWITCHER® switching regulators
1	When ordering, please specify Tolerance and packaging codes: e.g. DO3316P-105MLD
	Packaging:	D = 13" reel, machine-ready  EIA-481 embossed plastic tape (1000 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 D instead.
	Tolerance:	M = 20%, K = 10% (Table above shows stock tolerances in bold.)

2	Inductance tested at 100 kHz, 0.1 Vrms
3	Tolerances in bold are stocked for immediate shipment.
4	SRF >13 MHz measured using Agilent/HP8753D network analyzer; <13 MHz using Agilent/HP 4192A
5	Isat: DC current at which the inductance drops 10% (typ) from its value without current.
6	Irms: Current that causes a 40°C temperature rise from 25°C ambient. Details
7	Ambient temperature range:	–40°C to +85°C with Irms current. +85°C to +125°C with derated current Derating curve
8	Storage temperature range:	Component: –40°C to +125°C Packaging: –55°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.
