Document 776-1 Dual Inductors for Class-D Dual inductors for use in Class-D output filters AEC + Q200 125C 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 Core material Ferrite Terminations RoHS compliant tin-silver (96.5/3.5) over copper. Weight 5.0 g Ambient temperature 40C to +125C with Irms current Maximum part temperature +165C (ambient + temp rise) Storage temperature Component: 40C to +165C. Tape and reel packaging: 40C to +80C Resistance to soldering heat Max three 40 second reflows at +260C, parts cooled to room temperature between cycles Moisture Sensitivity Level (MSL) 1 (unlimited floor life at <30C / 85% relative humidity) PCB washing Tested to MIL-STD-202 Method 215 plus an additional aqueous wash.

When ordering, please specify packaging code: Output Power HA4158-ELD Temperature Packaging: D = 13 machine-ready reel. EIA-481 embossed plastic Power rise from 25C Test tape. Quantities less than full reel available: in tape typ (W) (C) Load THD+N condition (not machine ready) or with leader and trailer ( 25 charge). 22 10.0 4 Ohm 1% 1 kHz, 14.4 Vdc B = Less than full reel. In an effort to simplify our part 26 10.2 4 Ohm 10% 1 kHz, 14.4 Vdc numbering system, Coilcraft is eliminating the need 46 21.8 4 Ohm 1% 1 kHz, 21 Vdc for multiple packaging codes. When ordering, simply change the last letter of your part number from B to D. 56 22.8 4 Ohm 10% 1 kHz, 21 Vdc 2. Maximum power into specified load that causes less than a 40C 36 27.8 2 Ohm 1% 1 kHz, 14.4 Vdc temperature rise. Measured at 1 kHz with a 14.4 Vdc supply for the 44 25.1 2 Ohm 10% 1 kHz, 14.4 Vdc 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 25C ambient. This information is for reference only and does not represent absolute maximum ratings. 9. Electrical specifications at 25C. Refer to Doc 362 Soldering Surface Mount Components before soldering.
