Power DC-Link film capacitor targets automotive and green energy applications
KEMET has announced the C4AK high temperature, power film DC-Link capacitor designed specifically for continuous operation up to 1,000 hours at 135℃.
The C4AK series joins the C4AU (harsh environment) and C4AQ-P (125°C) family of power DC-Link film capacitors which offer higher capacitance density, DC voltage, and DC ripple current capabilities with an extended operational lifetime at high temperatures in harsh environments.
Intended for use in automotive, green, and industrial applications, these metallized film capacitors are suited for DC filtering and DC-Link in solar, fuel cells, inverters, storage energy systems, automotive (Bi) On-Board Charger, Wireless Power Transfer (WPT), DC/DC, heaters, and welding equipment.
The KEMET DC-Link C4AK film capacitor provides design features that include a radial box style for PCB mounting, miniaturization, low profile, 2 – 4 leads, and fewer capacitors needed in parallel to meet the required peak and ripple current.
The C4AK film capacitor surpasses the extreme conditions of the standard automotive (AEC-Q200) requirements for film technology in severe humidity/temperature conditions and offers greater performance with a lifetime of 4,000 hours at 125°C and 1000 hours at 135°C in harsh environmental conditions.
The C4AK DC-Link film capacitor’s extended life at high temperatures provides designers with a miniaturised, reduced component count solution over conventional film capacitors, particularly in Wide Band Gap high frequency, high current systems.
