Storage choke for audio amplifiers

29 April 2020 Passive Components

With WE-HIDA, Würth Elektronik offers a storage choke optimised for Class D amplifiers. The high-current inductor is characterised by low core losses, very low DC resistances from 2,5 mΩ to 14,8 mΩ and high saturation currents. WE-HIDA is not only available as a single inductor, but also in 2-in-1 designs (package sizes 1415 and 1521) for compact BTL (bridge-tied-load) applications.

In order to achieve the lowest possible total harmonic distortion in audio applications, the inductance values of the WE-HIDA have been selected to suit the most common filter topologies and have also been specifically tested. The THT (through-hole technology) high-current inductor is offered in 1415, 1480, 1521, 1715 and 3119 packages and in different versions with saturation currents from 6,5 A to 58 A. The operating temperature is specified for -40°C to +125°C.
