1. When ordering, please specify termination, and packaging codes:
GA3416-CLD
Termination: L = RoHS compliant tin-silver (96.5/3.5) over copper(leads), gold over nickel over phos bronze (additionalmounting 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). Quantities less thanfull reel available: in tape (not machine ready) orwith leader and trailer ($25 charge).
B = Less than full reel. In an effort to simplify our partnumbering system, Coilcraft is eliminating the needfor multiple packaging codes. When ordering, simply
change the last letter of your part number from B to D.
2. Maximum power into specified load that causes a 40°C temperaturerise. 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 thespecified temperature rise from 25°C ambient. This information is forreference only and does not represent absolute maximum ratings.
9. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
