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-BLandJA4575-ALnotrecommendedfornewdesigns

• Designed for low distortion and the best sound quality

Core material Ferrite

Terminations RoHS compliant tin-silver (96.5/3.5) over copper.

Weight 5.0 g

Ambient temperature –40°C to +125°C with Irms current

Maximum part temperature +165°C (ambient + temp rise)

Storage temperature Component: –40°C to +165°C.

Tape and reel packaging: –40°C to +80°C

Resistance to soldering heat Max three 40 second reﬂows at

+260°C, parts cooled to room temperature between cycles

Moisture Sensitivity Level (MSL) 1 (unlimited ﬂoor life at <30°C /

85% relative humidity)

Failures in Time (FIT) / Mean Time Between Failures (MTBF)

38 per billion hours / 26,315,789 hours, calculated per Telcordia SR-332

PCB washing Tested to MIL-STD-202 Method 215 plus an additional

aqueous wash. See Doc787_PCB_Washing.pdf.

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.
