|1||When ordering, please specify termination and packaging codes: e.g. MSD1048-224KED|
|Termination:||E = 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 (800 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 each winding, measured at 100 kHz, 0.1 Vrms, 0 Adc on an Agilent/HP 4284A LCR meter or equivalent. When leads are connected in parallel, inductance is the same value. When leads are connected in series, inductance is four times the value.|
|3||DCR is for each winding. When leads are connected in parallel, DCR is half the value. When leads are connected in series, DCR is twice the value. DCR at 25°C. For other operating temperatures, use this DCR at Temperature calculator.|
|4||SRF measured using an Agilent/HP 4191A or equivalent. When leads are connected in parallel, SRF is the same value. Details|
|5||Leakage Inductance is for L1 and is measured with L2 shorted.|
|6||Isat: DC current, at which the inductance drops 30% (typ) from its value without current. It is the sum of the current flowing in both windings. Details|
|7||Irms, both windings: Equal current when applied to each winding simultaneously that causes a 40°C temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings. Determine temperature rise.|
|8||Irms, one winding:
Current when applied to one winding that causes a 40°C temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings.
Determine temperature rise.
|9||Ambient temperature range:||−40°C to +85°C with Irms current.|
|10||Storage temperature range:||Component: –40°C to +125°C
Tape and reel packaging: –40°C to +80°C
|11||Maximum part temperature: +125°C (Ambient + temperature rise)|
|12||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.|
|13||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.|
