Vishay has introduced the first device in its new IHLD series of low-profile, high-current dual inductors. Offering two inductors in one 4032 package, the space-saving, automotive-grade IHLD-4032KB-5A is the industry’s first dual inductor to offer a high operating temperature range of up to 155°C.
An advantage of using a dual inductor such as the IHLD-4032KB-5A is that it reduces the requirement for board space when compared to an equivalent circuit using two discrete inductors, at the same time as offering improved performance.
A Class D audio amplification circuit using the IHLD-4032KB-5A can produce high-quality sound with low distortion, while suffering from low coupling, resulting in minimal cross-talk between the inductors. The new dual inductor offers excellent temperature stability for inductance and saturation over its operating range, which is as low as -55°C. Maximum current is rated at 5.6A.
