1 When ordering, please specify termination code: e.g. DO3340H-105KLD
  Termination: L = RoHS compliant tin-silver-copper over copper.
Special order, added cost: S = non-RoHS tin-lead (63/37).
  Packaging: D = 13" reel, machine-ready 
EIA-481 embossed plastic tape (350 per full reel). Quantities less than full reel available: in tape (not machine ready) or with leader and trailer ($25 charge).
2 Inductance tested at 10 kHz, 0.1 Vrms, 0 A using an Agilent/HP 4263B LCR meter or equivalent.
3 SRF measured using Agilent/HP 8753D network analyzer.
4 Isat: DC current at which inductance drops 30% (typ) from its value without current. For other operating temperatures, use this DCR at Temperature calculator.
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 +85°C with Irms current.
7 Storage temperature range: Component: −40°C to +125°C
Tape and reel packaging: −40°C to +80°C
8 Maximum part temperature: +125°C (Ambient + temperature rise)
9 Resistance to soldering heat: Max 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.
