1 When ordering, please specify termination and packaging codes: e.g. DO1608C-105MLC
  Termination: L = Gold over nickel over moly-manganese terminations
Special order, added cost: T = RoHS tin-silver-copper (95.5/4/0.5) or
S
= non-RoHS tin-lead (63/37).
  Tolerance: K = 10%, M = 20% (Table shows stock tolerances in bold.)
  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, 0 Adc using an Agilent/HP 4263B LCR meter or equivalent.
3 Tolerances in bold are stocked for immediate shipment
4 DCR measured at 25°C on a micro-ohmmeter. For other operating temperatures, use this DCR at Temperature calculator.
5 Isat: DC current at 25°C that causes a 10% (typ.) inductance drop from its value without current.
Temperature derating curves.
6 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.
7 Ambient temperature range: −40°C to +85°C with Irms current.
8 Storage temperature range: Component: −40°C to +125°C
Tape and reel packaging: −40°C to +80°C
9 Maximum part temperature: +125°C (Ambient + temperature rise)
10 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.
11 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.
