Storage choke against harmonic distortion

29 April 2020 Passive Components

The WE-LHMD is an SMT-mountable storage choke from Würth Elektronik optimised for filter topologies in Class-D amplifiers. Thanks to their iron powder cores, the high-current inductors for audio applications (available in 1008 and 1213 packages) display stable behaviour at high peak currents.

The WE-LHMD features the 2-in-1 design from non-coupled inductors and is therefore suitable for compact BTL (bridge-tied load) applications. The inductors are characterised by high saturation currents from 13 A to 25 A and low DC resistances from 16 mΩ to 104 mΩ. The operating temperature is specified for -40°C to +125°C.
