1 Packaging: D = 13" reel, machine-ready 
EIA-481 embossed plastic tape (600 parts per full reel).
2 Inductance is for the primary measured at 250 kHz, 1.0 Vrms, 0 Adc
3 Leakage inductance is for the primary and is measured with the secondary shorted.
4 Isolation (hipot) measured between windings for one minute.
5 DC current that causes an inductance drop of 20% (typ) from its value without current.
6 Ambient temperature range: −40°C to +125°C
7 Storage temperature range: Component: −40°C to +165°C
Tape and reel packaging: −40°C to +80°C
8 Maximum part temperature: +165°C
9 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.
10 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.
