Dual Inductors for Class D
• Dual inductors for use in Class D output filters
• A single shielded package contains both coils.
• Very low magnetic coupling
• AEC-Q200 Grade 1 qualified
• SMT (HA4158-EL) and through-hole (JA4575-BL) versions
• HA4158-BL and JA4575-AL not recommended for new designs
• Designed for low distortion and the best sound quality

1. When ordering, please specify packaging code:
HA4158-ELD
Packaging: D = 13″ machine-ready reel. EIA-481 embossed plastic
tape.
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 less than 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 100 kHz, 1.0 Vrms, 0 Adc using an Agilent/
HP 4284A impedance analyzer.
4. DCR is for each winding, measured on a micro-ohmmeter.
5. SRF measured using Agilent/HP 8753D network analyzer.
6. Total harmonic distortion + noise measured at 20 W into a 2­‑Ohm or
4‑Ohm load at 1 kHz with a 21 Vdc supply.
7. DC current (typical) at which the inductance drops the specified
amount 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.
