14: TDK-EPC Announces PhaseCap Compact PFC Capacitors With Extended Voltage Range

TDK-EPC, a group company of the TDK Corp., has extended its range of power factor correction (PFC) capacitors: the EPCOS PhaseCap® Compact series now also includes types with voltages of 690, 800, 900 and 1000V. The capacitors of the B25673AA series offer PFC values of between 5 kvar (50 Hz) and 33 kvar (60 Hz) at capacitance values of between 3 x 11 and 3 x 55µF. Thanks to their compact design with diameters of only 116 and 136mm at insertion heights of 164 and 200mm, these capacitors are particularly useful for designing space-saving PFC systems for industrial networks.

12: Wurth Electronics Dual Coil Combines High Common & Differential Mode Impedance for LED Lamps

Wurth Electronics Midcom, a designer and manufacturer of custom magnetic components, created the Dual Coil series of common mode chokes with high dual impedance capabilities – in what the company says is the smallest package size on the market today. The Dual Coil series of common mode chokes offer what the company describes as a cost-effective solution for suppression of common mode and differential mode impedance at low frequencies, ranging from 10kHz to 100MHz. The dual feature eliminates the need for multiple components, which saves cost on the bill of materials and space on the printed circuit board.
