At PCIM Europe, the trade show for power electronics which was held in Nuremberg from 16–18 May 2017, Würth Elektronik exhibited its broad-based portfolio of electronic and electromechanical components and unveiled a whole range of new products.
The WE-HCF, now available in 2815 package, is a flat wire power inductor with very high current loading capacity and efficiency. The inductor’s large wire cross-section makes its resistance 13% lower than comparable products on the market and it attains up to 82% higher saturation current. The component, specified up to 125°C, is suitable as a highly efficient DC-DC converter or for filtering audio applications.
WE-DPC HV (Double Power Choke High Voltage) range are the smallest coupled power chokes yet in the Würth Elektronik eiSos portfolio. The flexibly deployable SMD transformer WE-FLEX HV with an isolation voltage of 1,5 kV a.c. features a newly developed MnZn core material that reduces core losses by up to 30% as compared to classical products and makes the new SMD transformer an attractive solution for all types of isolated DC-DC converters in industrial and telecommunications applications.
With its WE-ACHC (Air Coil High Current), Würth presented a new family of high-current air coils for HF applications. The flat wire coils are available in 1010 and 1212 packages and in various inductance values. The coil label enables pick and place assembly. Application examples include high-frequency VRMs (voltage regulator module) in MRIs and other devices in which no magnetic materials may be used.
Würth is active on wireless power standards bodies and now offers one of the broadest ranges of coils for this growth field. Four other transmission coils debuted at PCIM Europe belong to the WPCC series with NiZn ferrite shielding to protect sensitive electronics and concentrate the magnetic field. The features of these coils are the transmission power up to 200 W and their very low resistance. One of the new coils is especially designed for resonant inductive coupling and can be also used with several receivers at the same time.
The WE-LAN AQ shielded LAN transformer excels with its particularly flat 4 mm housing and improved soldering properties, thanks to gold plated half-vias. Apart from that, the LAN transformer also displays outstanding return loss / crosstalk properties and is specified for the industrial temperature range of -40°C to +85°C.
The new WR-BTB board-to-board connector series was developed for particularly fast and reliable data connection. WR-TBL are new SMT assembly terminal blocks and, with WR-LECO, represent a family of LED plug-in connectors. Another focus area of the mechanical components is switches – here Würth showcased a series of new, highly robust models.
