Stackpole Electronics introduced the HCC series high-current busbar shunts for battery electric and hybrid vehicle current sensing applications. Designed for battery management systems, DC bus measurement and inverter output current monitoring, the series supports current handling above 1400A with resistance values of 100, 50 and 25µOhm. Features all-welded construction for mechanical durability and linear current measurement output across high-current EV subsystems. Available in multiple package sizes and resistance values, the shunts are intended for scalable EV and hybrid power system designs. Stackpole also offers custom sizes, shapes and resistance values through its vertically integrated manufacturing operations.
Henkel expanded its Technomelt portfolio with the PA 6370 low-pressure molding material for electronic assemblies requiring fine-gap filling and environmental protection. Polyamide-based hot melt formulation supports gap penetration down to 0.5mm with ultra-low melt viscosity from 2700–3000mPa·s at 210°C and 1065–1180mPa·s at 240°C. Material provides adhesion stability across multiple substrates and passed lap shear testing after 1,200hr exposure to 85°C/85% RH conditions. Technomelt PA 6370 meets UL 94 V-0 flame retardancy requirements and offers electrical insulation properties with a coefficient of thermal expansion of 175ppm. Operating temperature range spans -20°C to 140°C. Henkel said the material supports low-pressure molding processes with cycle times as low as 30 sec., targeting faster encapsulation compared to conventional potting approaches.
RVCU series high-voltage chip resistors support voltage divider, sensing and measurement circuits requiring stable high-voltage performance. Features voltage coefficient of resistance values from 25ppm–50ppm, lower than conventional high-voltage chip resistors, for improved precision in voltage divider applications. Available in 1206, 2010 and 2512 package sizes with working voltages from 800V–3000V, tolerances to 0.5% and 100ppm TCR. Includes anti-sulfur construction per ASTM-B-905-5 and IEC-62368 compliance for values from 75kΩ–27MΩ. Intended for LED lighting, medical equipment, communications systems, test and measurement instruments and high-voltage control applications.
