3D Model Datasheet Inductors for Class-D audio

RA7231 Series

Dual Inductor for Class-D output filters

Coilcraft's RA7231 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
AEC-Q200 Grade 1 (−40°C to +125°C)

메모

When ordering, please specify packaging code: e.g. RA7231-ALD
Inductance is for each winding, measured at 100 kHz, 1.0 Vrms, 0 Adc using an Agilent/HP 4284A impedance analyzer. Minimum inductance is 4.5 µH at 11.5 Adc.
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.
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 25°C ambient.

종단 처리:

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

패키지:

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.
