1 Packaging: D = 13" reel, machine-ready reel
EIA-481 embossed plastic tape. Quantities less than full reel available: in tape (not machine ready) or with leader and trailer ($25 charge).
2 Inductance measured at 100 kHz, 1.0 Vrms, 0 Adc using an Agilent/HP 4284A impedance analyzer.
3 DCR is for each winding, measured on a micro-ohmmeter at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
4 SRF measured using Agilent/HP 8753D network analyzer.
5 Isat: DC current (typical) at which the inductance drops the specified amount from its value without current.
6 Irms: Current applied to both windings at the same time that causes the specified temperature rise from 25°C°ambient. This information is for reference only and does not represent absolute maximum ratings.
7 Ambient temperature range: −40°C to +125°C with Irms current
8 Storage temperature range: Component: −40°C to +165°C
Tape and reel packaging: −40°C to +80°C
9 Maximum part temperature: +165°C (Ambient + temperature rise)
10 Resistance to soldering heat: Max three 40 second reflows at +260°C for 40 seconds, parts to cool to room temperature between cycles.
11 Electrical specifications at 25°C.
