HA4158-EL and JA4575-BL Series

Dual Inductors for Class-D output filters

The HA4158-EL and JA4575-BL Series are newer, more cost-effective replacements for the HA4158-BL and JA4575-AL. They are identical in form, fit, function and performance. View old data sheet.

Coilcraft's HA4158-EL and JA4575-BL Series uncoupled dual inductors provide two back-to-back inductors that operate independently without coupling effects. This unique design saves space by combining two inductors in a single package. They are perfect for Class-D applications.

Designed for low distortion and the best possible sound quality.
Shielded package contains both coils.
Very low magnetic coupling
SMT (HA4158-EL) and through-hole (JA4575-BL) versions.
AEC-Q200 Grade 1 (−40°C to +125°C)

Notes

When ordering, please specify termination and packaging codes: e.g. HA4158-ELD
Inductance is for each winding, measured at 100 kHz, 1.0 Vrms, 0 Adc using an Agilent/HP 4284A impedance analyzer.
DCR is for each winding, measured on a micro-ohmmeter at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
SRF measured using Agilent/HP 8753D network analyzer.
Total harmonic distortion + noise measured at 20 W into a 2-Ohm or 4-Ohm load at 1 kHz with a 21 Vdc supply
Isat: DC current (typical) at which the inductance drops the specified amount from its value without current.
Irms: Current applied to both windings at the same time that causes the specified temperature rise from 25Â°C ambient. This information is for reference only and does not represent absolute maximum ratings.

Termination:

L = RoHS compliant tin-silver over copper.
T = RoHS tin-silver-copper (95.5/4/0.5). (Special order, added cost)
S = non-RoHS tin-lead (63/37). (Special order, added cost)

Packaging:

D = 13″ machine-ready reel. EIA-481 embossed plastic tape. Quantities less than full reel available: in tape (not machine ready) or with leader and trailer ($25 charge).
B = Less than full reel. In an effort to simplify our part numbering system, Coilcraft is eliminating the need for multiple packaging codes. When ordering, simply change the last letter of your part number from B to D.
