New Industry Products

New Tantalum Polymer Capacitors, Super Capacitors and Aluminum Capacitors

August 27, 2020 by Alessandro Mascellino

In this month’s capacitor product recap we take a look at transistors from Kemet, Vishay, and Cornell Dubilier.

This recap showcases power MOSFETs products for different applications, including alternative energy, welding equipment, and IoT systems.


Tantalum Polymer Capacitors From KEMET

These new capacitors from KEMET are built to provide the highest capacitance/voltage (CV) ratings in surface mount device (SMD) capacitors.

The components have an innovative stacking construction that allows engineers to customize designs for capacitance, voltage, and low ESR (equivalent series resistance).

Because of this, the capacitors work flawlessly with Gallium Nitride (GaN) semiconductor technology, making them ideal for radar applications based on the Active Electronically Scanned Array (AESA) systems.

Moreover, due to its improved derating conditions and larger capacitance, the TSP series is qualified for diversified applications such as airborne, grounded, and naval equipment.

The new capacitors are already available on KEMET’s website, and you can read more information about them at this link here.


ESR Super Capacitors From Cornell Dubilier Electronics

Cornell’s new DGH Series includes 24 different values and voltage combinations, ranging in capacitance from 0.5F (Farad) to 600F, and featuring voltage ratings from 2.7 to 5.5WVDC (Working Voltage Direct Current).

The components’ operating temperatures range from -40 ºC to 65 ºC at maximum WVDC, or from -40 ºC to 85 ºC at 2.3 volts.

The DGH Series is the latest addition to Cornell’s Illinois Capacitor brand and expands the line by adding capacitance values up to 600 Farads.

For maximum versatility, multiple capacitors can be banked in parallel or series to achieve even higher voltage or capacitance.

DGH supercaps are built to discharge instantaneous bursts of power, making these components ideal for energy harvesting, IoT systems, mechanical actuators, and more.

Snap-in Power Aluminum Capacitors From Vishay Intertechnology

Introduced by Vishay earlier this month, the BCcomponents 193 PUR-SI series comprises a number of miniature snap-in power aluminum electrolytic capacitors that enable higher power density designs.

Featuring ripple currents up to 3.27 A and longer useful life of 5,000 hours at +105 °C, the news series enables engineers to save board space while also reducing costs.

The BCcomponents 193 PUR-SI series has been built to be RoHS-compliant and is housed in a cylindrical aluminum case, insulated with a blue sleeve.

The components’ rated voltages are 500 V, and the series comes in 25 compact case sizes ranging from 22 mm by 25 mm to 35 mm by 60 mm.

The new capacitors are polarized aluminum electrolytic with a non-solid electrolyte.

This makes them suited for smoothing, buffering, and DC-Link filtering in switch-mode power supplies, motor drives, as well as solar inverters, industrial air conditioners, and welding equipment.

Samples of the BCcomponents 193 PUR-SI series are already available on Vishay’s website, with lead times of 12 weeks.
