1210uT Series

Dual Inductors for A²B® Audio Bus

Automotive Audio Bus (A²B^®) by Analog Devices transmits audio and control data in vehicles, reducing wiring complexity and improving sound quality. Our 1210uT inductors filter high-frequency noise and ensure balanced power injection in A²B^® systems. They combine two inductors into a single package, offering higher current capability and matching the impedance performance of two single inductors on the market.

Optimized for Analog Devices’ A²B® audio bus, where low imbalance minimizes mode conversion in balanced power injection applications and a coupling factor of less than 10% is required
1210-sized dual Inductor with tightly controlled balanced inductance, within a maximum 10% imbalance
AEC-Q200 qualified

Hinweise

When ordering, please specify termination and packaging codes: e.g. 1210uT-103MRC
Inductance measured per winding at 100 kHz, 0.1 V, 0 Adc.
DCR is per winding, measured on a micro-ohmeter.
Isat: DC current at the specified ambient temperature that causes a 30% inductance drop from its value without current.
Irms: Current applied to both windings at the same time causes a 40C rise from the specified 25°C and 85°C ambient temperatures, and a 15°C rise at 125°C ambient temperature. This information is for reference only and does not represent absolute maximum ratings.

Anschlüsse:

R = RoHS compliant matte tin over nickel over silver-platinum-glass frit.
Q = RoHS tin-silver-copper (95.5/4/0.5). (Special order, added cost)
P = non-RoHS tin-lead (63/37). (Special order, added cost
