A unique composition for special conductivity: Rutronik introduces MLCCs from KEMET with KONNEKT technology

09/07/2023 Product News

KEMET realizes the connection of several MLCCs to a single surface-mountable component with its KONNEKTTM technology. It is a high-density housing technology that can connect components without a metal frame. That helps to significantly reduce the equivalent series resistance (ESR), equivalent series inductance (ESL), and thermal resistance of capacitors. The surface-mount U2J, KC-LinkTM, and C0G capacitors are primarily designed for power applications with high efficiency and high packing density. KEMET's X7R series capacitors are used when higher capacitances and voltages are required additional space on the PCB. The capacitors (U2J, KC-LinkTM, X7R, and C0G) are available with case sizes 1812, 2220 and 3640 at www.rutronik24.com.

KONNEKTTM technology uses an innovative TLPS (Transient Liquid Phase Sintering) material in which a low melting point metal or alloy reacts at low temperature with a high melting point metal or alloy to form a reactive metal matrix. The result is a highly conductive interconnect material that can be used to join multiple MLCCs. The result is stacked "multi-chip" devices without lead frames that can be aligned horizontally and vertically. This makes it easy to reduce the space required on the PCB.

Benefits at a glance:

  • Space saving on the PCB
  • Low ESR and ESL
  • High ripple current
  • Commercial and automotive quality
  • C0G(NP0), U2J(N750) and X7R dielectrics
  • Wide temperature range from -55 °C up to +150 °C

Other applications:

  • Wide bandgap (WBG), silicon carbide (SiC), and gallium nitride (GaN) based systems
  • Data centres
  • EV/HEV (drive systems, charging)
  • LLC resonant converters
  • Switched tank converters
  • Wireless charging systems
  • Photovoltaic
  • Power converters
  • Inverter
  • DC link
  • Snubber
