TDK Corporation (TSE: 6762) presents ModCap™ − a modular capacitor concept for DC link applications. The newly developed power capacitors are available for rated voltages of 1100 V to 2300 V and cover a 365 µF to 2525 µF capacitance range. The rated currents between 105 A and 180 A are type-conditioned with all types designed for 5 kA recurrent pulse currents. The maximum permitted hot spot temperature is 90 °C.
Large supercapacitors now compete for head-on with batteries and are quoted in kWh. Some are drop-in lead-acid and lithium-ion battery replacements. Others are bought as uninterruptible power supplies up to 1MWh offering the bonus of efficient peak-shaving because power density is ten times that of lithium-ion batteries and series resistance low.
High voltage chip capacitors are constructed to filter out electromagnetic interference (EMI) and smooth output voltages and built for applications up to 2500VDC. They are small, leadless, and can easily be placed on a PCB.
PREMO, leader in manufacturing RFID magnetic sensors, Inductive couplers and power magnetic components completes its range of signal transformer with this SMD PLC-LW series. Providing a more competitive (low cost) product using Linear Winding versus Toroidal winding.
This series fulfills the growing need for increased reliability of tantalum polymer capacitors beyond currently available commercial grade solutions for both commercial avionic applications and automotive applications, such as advanced driver-assistance systems (ADAS).
One of the most enduring trends in the electronics industry is miniaturization. Advances in semiconductor technology, such as the implementation of wide-bandgap (WBG) MOSFET and diode devices, emphasize reducing the size of electronic components while significantly improving performance
