Precision Current Sensing & Resistance Technology

Precision measurement at the current-sensing point

MarlinTek's approved Isabellenhütte portfolio includes precision alloy shunt resistors, low-resistance current-sensing technologies and modular measurement systems. These technologies are relevant where current measurement affects protection, control, monitoring or power-management decisions.

Engineering characteristics

The customer baseline identifies ultra-low TCR, high continuous power ratings and long-term stability in harsh environments as key characteristics of the portfolio.

Applications

• EV charging infrastructure
• Battery management systems
• Motor drives
• Precision power measurement
• Industrial power electronics

Selection considerations

Current-sensing selection should consider resistance value, temperature coefficient, continuous and transient loading, thermal environment, mechanical construction and long-term stability. It should also be considered alongside the switching devices, capacitors and magnetic components in the same power path.
