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 DCR measured at 25°C on a micro-ohmmeter. For other operating temperatures, use this DCR at Temperature calculator.
4 Isat: DC current at 25°C that causes a 10% (typ) inductance drop from its value without current.
Temperature derating curves.
5 Irms: Current that causes a 20°C 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 +85°C with Irms current.
7 Storage temperature range: Component: −40°C to +105°C
Tape and reel packaging: −40°C to +80°C
8 Maximum part temperature: +105°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.
