1 When ordering, please specify termination code: e.g. SER2211-473MEC
  Termination: E = RoHS compliant matte-tin over nickel over phos bronze. 
Special order: Q = RoHS tin-silver-copper over copper
(95.5/4/0.5) or P = non-RoHS tin-lead (63/37).
  Packaging: D = 13" reel, machine-ready 
EIA-481 embossed plastic tape (200 parts per full reel). Quantities less than full reel available: in tape (not machine ready) or with leader and trailer ($25 charge).
2 Inductance measured at 100 kHz, 0.1 Vrms, 0 Adc on an Agilent/HP 4284A or equivalent.
3 DCR measured at 25°C on a micro-ohmmeter. For other operating temperatures, use this DCR at Temperature calculator.
4 SRF measured using an Agilent/HP 4391A impedance analyzer and an Agilent/HP 16193A test fixture. Details
5 Isat: DC current at 25°C that causes the specified inductance drop from its value without current.
Temperature derating curves.
6 Irms: Current that causes a 40°C temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings. Temperature derating curves. When Irms is greater than Isat, Isat is the more critical specification and Irms is shown in gray type. See temperature rise vs Current.
7 Ambient temperature range: −40°C to +85°C with (40°C rise) Irms Derating curves
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 + temp 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.
