1. When ordering, please specify termination, and packaging codes:

II-

GA3416-CLD

= RoHS compliant tin-silver 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).

Termination: L

Packaging:

D = 13" machine-ready reel. EIA-481 embossed plastic

tape (400 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 which the inductance drops the specified amount from its value without current.

8. Current applied to windings connected in series that causes the specified temperature rise from 25°C ambient.

9. Electrical specifications at 25°C.

See Qualification Standards section for environmental and test data. Refer to Doc 362 "Soldering Surface Mount Components" before soldering.
