1	When ordering, please specify termination and packaging codes: e.g. DO3340P-105MLD
	Termination:	L = Gold over nickel over phos bronze. Special order, added cost: T = RoHS tin-silver-copper (95.5/4/0.5) or S = non-RoHS tin-lead (63/37).
	Packaging:	D = 13" reel, machine-ready EIA-481 embossed plastic tape (225 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.

2 Inductance tested at 100 kHz, 0.1 Vrms using an Agilent/HP 4263B LCR meter or equivalent.

3 Isat: DC current at which the inductance drops 10% (typ) from its value without current. Details

4 Irms: Current that causes a 20°C temperature rise from 25°C ambient. Details

5 Ambient temperature range: –40°C to +85°C with Irms current.
+85°C to +105°C with derated current Derating curve

6 Storage temperature range: Component: –40°C to +105°C
Packaging: –55°C to +80°C

7 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.

8 Electrical specifications at 25°C.

See Qualification Standards for complete environmental and test data.
