Farnell element14 expands KEMET capacitor offering

Farnell element14 now stocks KC-LINK Surface Mount Capacitors from KEMET, manufacturers of advanced capacitors and components.

The KC-LINK surface mount capacitors are designed to meet the growing demand for fast switching semiconductors that operate at a higher voltage, temperature and frequency. With an operating temperature of up to 150°C, these capacitors can be mounted close to fast switching semiconductors at very high power density applications, which require minimal cooling.

KEMET utilizes a proprietary C0G/NPO base metal electrode dielectric system, making the capacitors well suited for power converters, inverters, snubbers and resonators, where high efficiency is a primary concern. With extremely low effective series resistance (ESR) and very low thermal resistance, KC-LINK capacitors can operate at very high ripple currents with no change in capacitance versus DC voltage and negligible change in capacitance versus temperature.

The KC-Link C0G dielectric technology also provides high mechanical robustness compared to other dielectric technologies, allowing the capacitor to be mounted without the use of lead frames. This provides extremely low effective series inductance (ESL) that increases the operating frequency range, allowing further miniaturization.

Other benefits include an operating temperature range of −55°C to +150°C, high frequency operation (>10 MHz), no piezoelectric noise and the capacitors are also RoHS Pb-free. Automotive grade devices are also available to meet the demanding Automotive Electronics Council’s AEC–Q200 qualification requirements.

Typical applications include:

  • Wide bandgap (WBG), silicon carbide (SiC) and gallium nitride (GaN) systems

  • Hybrid electrical vehicles (drive systems, charging)

  • Photovoltaic systems

  • Power conversion

  • Inverters

  • DC link

  • LLC resonators

  • Snubber

KEMET KC-LINK surface mount capacitors are now available to buy from Farnell element14 in Europe and Newark element14 in North America.

Next Generation Freight Transport Mark Patrick | mouser Electronics
Next Generation Freight Transport
As road freight transport levels continue to grow, concerns about the impact on the environment and human health come sharply into focus. Fossil fuel dependency makes it a leading source of greenhouse gas (GHG) emissions, but shifting freight to other transportation modes will prove challenging. Solutions that will improve the efficiency and performance of road freight transport are therefore essential to achieve defined environmental goals. In this blog, we will explore a potential solution that has been pioneered by Siemens - called eHighway. This combines the efficiency of electrified railways with the flexibility of trucks in order to form an innovative, next generation freight traffic system that is efficient, economical and environmentally friendly.
