Mersen MHi-T High Temperature Bus Bars

Mersen MHi-T High Temperature Bus Bars

Oct 5, 2020

Using a combination of polyaramid dielectric insulation and high temperature adhesive, MHi-T High Temperature Bus Bars are designed to respond to increased temperature rises in Wide Band Gap technology systems. While traditional laminated bus bars are limited to a working temperature of 105°C, Mersen’s MHi-T bus bars allow for increased working temperatures up to 180°C.

Today’s customers turn to Wide Band Gap (WBG) technologies such as SiC and GaN based power modules to increase power densities in their drives and inverters designs. Due to their inherent nature, WBG modules introduce an increased level of heat into their laminated bus bars connectors. Increased temperature rises on standard laminated bus bars may cause partial or complete breakdown of the bonding agent (glue) of the insulation, causing the insulation to lift and separate from the conductor surface, creating potential unsafe shock or short circuit faults. Mersen MHi-T laminated bus bars address this increased temperature rise in WBG power modules with higher temperature tolerances.
