Termination: L =RoHS compliant tin-silver (96.5/3.5) over copper
(leads), gold over nickel over phos bronze (additional
mounting pads.
Special order: T = RoHS tin-silver-copper (95.5/4/0.5)
or S = non-RoHS tin-lead (63/37).
Packaging:D
=13″ machine-ready reel. 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. Refer to Output Power table
for typical output conditions. Tested using the 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.
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.DC current at 25°C that causes the specified inductance drop from its
value without current.
8. 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. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
