Low-ohmic precision resistors are foundational to accurate current and power sensing — especially in mission-critical aerospace and defense systems. But designing resistors for space-grade and high-altitude applications involves far more than meeting electrical specifications. Environmental exposure, radiation tolerance, regulatory compliance, and long-term reliability all introduce unique engineering challenges.
In this 30-minute live webchat, we’ll explore how DLA-approved precision power resistors are engineered to meet the rigorous demands of aerospace, military, and NewSpace applications. From understanding temperature coefficient of resistance (TCR) and thermal stability to mitigating space-specific failure modes like tin whiskering, attendees will gain insight into what truly defines a high-reliability current-sense solution. We’ll also review the VMx and SMx series, including their specifications, qualification standards, and real-world aerospace deployments.
Key Takeaways:
– Why low-ohmic precision resistors are critical in battery management systems (BMS) and motor drives
– How aerospace radiation environments impact resistor design
– The role of DLA and ESCC qualification in streamlining aerospace certification
– Understanding tin whiskering and how SnPb plating mitigates risk
– Performance capabilities of the VMx and SMx DLA/ESCC-approved resistor series
– How to select the right footprint, wattage, and resistance range for aerospace applications
Join us to learn how precision resistor technology is enabling the next generation of reliable aerospace and defense systems.
