Würth Elektronik WE-HIDA high-current inductor

Würth Elektronik offers the WE-HIDA storage choke optimised for Class D amplifiers. The high-current inductor is characterised by low core losses, low DC resistances from 2.5 to 14.8 mΩ and high saturation currents. It is available as a single inductor as well as in two-in-one designs (package sizes 1415 and 1521) for compact BTL (bridge-tied load) applications.

In order to achieve low total harmonic distortion in audio applications, the inductance values of the device 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 to 58 A. The operating temperature is specified for -40 to +125°C.
