The Entire World of Passive Components

Würth Elektronik eiSos presents 2017 Product Catalog

Würth Elektronik eiSos, a leading European manufacturer of electronic and electromechanical components, has published its “Passive Components 2017” product catalog. Numerous products are presented on 776 pages in the categories EMC Components, Power Magnetics, Signal & Communications, and AEC-Q qualified products. The “Passive Components 2017” catalog can now be requested online at The same applies for the products described there: All the components listed are available from stock and samples can be obtained free of charge.

The new edition of the product catalog reveals a whole series of additional components and extended product families. The most important new products include the WE-CMB HV current-compensated mains choke for higher AC voltage ranges up to 760 V. It features a rated voltage three times higher than that of the existing WE-CMB series.

The new WE-TPB HV series of 3-phase current-compensated mains chokes was also developed for this voltage range. It excels by virtue of an innovative, patented design for plastic housing, separator and grid plate. Typical application areas include frequency converters and high power charging stations.

New materials and designs

The WE-CFWI series of coupled storage inductors with flat wire windings has two new packages with inductance values up to 10 μH. These coupled storage inductors are used with SEPIC and CUK switching controllers for which higher currents are required. Other highly interesting inductor innovations: the WE-KI HC ceramic high current inductor for high frequency applications, as used in the telecommunications sector for instance. The new series includes the two packages 0402 and 0603. The WE-PMMI metal alloy multilayer SMD storage inductor demonstrates Würth Elektronik eiSos’ confidence in working with new materials. Double-printed silver layers have led to a 75% reduction in DC resistance. A new method of coating with metal alloy nanoparticles helps achieve outstanding performance, as well as a voltage stability of 100 VDC.
