At PCIM Europe (Nuremberg, 16-18 May 2017), Würth Elektronik eiSos will exhibit intelligent drive technology, renewable energy and energy management. Located at booth 7-229 in Hall 7 at the Nuremberg Exhibition Center, the manufacturer presents its broad-based portfolio of electronic and electromechanical components and also unveils a whole range of new products. Highlights include the WE-HCF SMD high current inductor in 2815 package, WE-DPC HV magnetically shielded, coupled SMD power chokes, extremely efficient wireless power coils with up to 200W transferable power and the shielded LAN transformer WE-LAN AQ.

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 percent lower than comparable products on the market and it attains up to 82 percent higher saturation current. The component specified up to 125 degrees C is suitable as a highly efficient dc-dc converter or for filtering audio applications.

WE-DPC HV (Double Power Choke High Voltage) are the smallest coupled power chokes yet in the Würth Elektronik eiSos portfolio. With these products the manufacturer has managed to raise efficiency beyond that of comparable chokes. The flexibly deployable SMD transformer WE-FLEX HV with an isolation voltage of 1.5kVac is completely unrivaled on the market. The newly developed MnZn core material reduces core losses by up to 30 percent 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 Elektronik eiSos presents 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 & place assembly. Application example: High frequency VRMs (Voltage Regulator Module) in MRIs and other devices in which no magnetic materials may be used.

Würth Elektronik eiSos is very active on wireless power standards bodies and now offers one of the broadest ranges of coils for this growth field. Four other transmission coils celebrating their premiere at PCIM Europe belong to the WPCC series with NiZn ferrite shielding to protect sensitive electronics and concentrate the magnetic field. The outstanding features of these coils are the transmission power up to 200W 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 4mm 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 to +85 degrees C.

Development at Würth Elektronik eiSos does not stop at electromechanical components either. 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 WE eiSos present a family of LED plug-in connectors. Another focus area of the mechanical components is switches – here Würth Elektronik eiSos showcases a series of new, highly robust models.
