1When ordering, please specify termination and packaging codes: e.g. GA3416-CLD
  Termination: L = RoHS compliant tin-silver over copper (leads); gold over nickel over phos bronze (additional mounting pads.
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 (200 parts per full reel).
B = Less than full reel
In tape, but not machine-ready. To have a leader and trailer added ($25 charge), use code letter D instead.
2 Maximum power into specified load that causes a 40°C temperature rise. Measured at 1 kHz with a 14.4 Vdc supply for the 2-Ohm load and a 21 Vdc supply for the 4-Ohm load. Output Power table shows typical output conditions. Tested using TAS5414A evaluation board from Texas Instruments.
3 Inductance measured at 500 kHz, 0.5 Vrms, 0 Adc using an Agilent/HP 4284A impedance analyzer.
4 DCR measured on a micro-ohmmeter at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
5 SRF measured using Agilent/HP 8753D network analyzer.
6 Total harmonic distortion + noise measured at 23 W into a 2-Ohm or 4-Ohm load at 1 kHz with a 21 Vdc supply.
7 Isat: DC current at 25°C that causes the specified inductance drop from its value without current.
8 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.
9 Ambient temperature range: −40°C to +125°C with (40°C) Irms current
10 Storage temperature range: Component: −40°C to +165°C
Tape and reel packaging: −40°C to +80°C
11 Maximum part temperature: +165°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.
