1 When ordering, please specify termination and packaging codes: e.g. MSD1260-105KLD
  Termination: L = RoHS compliant matte tin 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 (500 parts per full reel).
B = Less than full reel
In tape, not machine ready. To have a leader and trailer added ($25 charge), use code letter D instead.
2 Inductance shown for coupled inductor and for two inductors connected in parallel.
3 Inductance tested at 100 kHz, 0.1 Vrms, 0 Adc, on an Agilent/HP 4263B LCR meter or equivalent.
4 DCR is for both windings connected in parallel. DCR for each winding is twice the value.
5 SRF measured using an Agilent/HP 4191A network analyzer or equivalent. Details
6 Isat: DC current at which the inductance drops 30% (typ) from its value without current. Details
7 Irms: Current that causes a 40°C rise from 25°C ambient. Details
8 DCR is for both windings.
9 Ambient temperature range: –40°C to +85°C with Irms current.
+85°C to +125°C with derated current Derating curve
10 Storage temperature range: Component: –40°C to +85°C
Packaging: –55°C to +80°C
11 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.
12 Electrical specifications at 25°C.
