Hobart Vault Update - Würth Elektronik

The Hobart Content Team is pleased to announce the release of Würth Elektronik’s SMD Power Chokes and Double Chokes. This is the fourth and final release of Würth components.  Eight categories have now been released over the last two months; an additional 1600 components available in the vault, all with detailed 3D support.

SMD Power Choke

The SMD power chokes of Würth are divided between magnetically shielded and unshielded inductors. The magnetically shielded inductors are represented by the families WE-PD, WE-PD3, WE-PDF, WE-TPC, and the power multilayer inductors WE-PMI. The families WE-PD2, WE-PD4, WE-GF and WE-LQ are magnetically unshielded.

The inductors are optimized for use in switching regulators and DC-DC converters, optimised in the selection of the core and winding design. Furthermore, these components realise a stable inductance over a wide range of frequencies. In the area of switching regulator applications, the choke is used for intermediate storage of electrical energy and also for smoothing the output current.

Nickel-Tin alloy used for the core results in very low losses and high modulations.  This makes them particularly suitable for use in switching regulator applications up to 10 MHz while they offer a high current capacity and low DC resistance in a very small package. The miniature power chokes WE-TPC are suitable for applications where a high package density and a low height are required.

Double Choke

The magnetically shielded WE-DD series of double chokes, in contrast to the single-wound inductors, have two identical, separate windings on a common ferrite core. The application spectrum of this reactor is large, it can be used in 1:1-flyback applications, buck, boost, SEPIC and CUK switching regulators and switching regulators with a second, unregulated output voltage. When using them in series and parallel arrangements, even more choke solutions become available.

All components are available from Würth Elektronik ex stock. Samples are available free of charge. More info at
