1 When ordering, please specify termination and packaging codes: e.g. DS1608B-105MLC
  Termination: L = Gold over nickel over moly-manganese
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 (750 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" reel, machine-ready 
EIA-481 embossed plastic tape. Factory order only, not stocked (2500 per full reel).
2 Inductance tested at 100 kHz, 0.1 Vrms.
3 DCR measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
4 Irms: Current that causes a 30°C temperature rise from 25°C ambient.This information is for reference only and does not represent absolute maximum ratings. Temperature derating curves.
5 Ambient temperature range: −40°C to +85°C with Irms current.
6 Storage temperature range: Component: −40°C to +115°C
Tape and reel packaging: −40°C to +80°C
7 Maximum part temperature: +115°C (Ambient + temperature rise)
8 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.
9 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.
