Isabellenhütte Heusler GmbH & Co. KG – Whenever highest reliability, precision and longevity are required, there is no way around the lowohmic precision and power resistors made in Germany.
It is not without reason that Isabellenhütte has been supplying resistors to the aerospace industry for more than twenty years:
ESCC qualified ISA-PLAN® technology precision resistors in the value range of 2.2 mOhm to 2 Ohm provide outstanding key Features (very high long-term reliability, small temperature coefficient, low inductance, low internal heat resistance, high to very high pulse power rating) to any kind of electronics using low-ohmic resistors for current monitoring and limiting purposes, such as
Power Supplies: Used in DC/DC converters for the decentralized
energy distribution in satellites
Battery Management: Monitoring Load/Unload operations ; used in
satellites and ground Vehicles
Failure Recovery: Used in SEL (Single-Event Latch-up) circuits

The annual German Aerospace Center’s (DLR) Components Conference brought together around 150 leading experts from the aerospace, industrial, and research sectors at Isabellenhütte over the course of two days. The conference focused on key future topics related to electronic space components: The spotlight was on current developments, industry requirements, and strengthening technological and industrial sovereignty in Europe—particularly along the supply chains for electrical, electronic, and electromechanical (EEE) components.
Industries such as marine engineering, chemical processing, power generation, and oil & gas extraction increasingly face the challenge of providing reliable materials for aggressive media, extreme temperatures, and long‑term stress. Conventional stainless steels and standard alloys frequently reach their limits here — especially in applications that require high corrosion resistance, mechanical strength, and stable material properties simultaneously. With the expansion of its ISA®-NICKEL portfolio, known in the market as Monel®, Isabellenhütte now offers a solution tailored to these exact demands.
Measurement specialist Isabellenhütte introduces an innovative series of pulse load resistors designed to absorb voltage spikes in power electronics used in automotive applications. These resistors protect downstream components from damage caused by electrical overstress. The PMx series features a flat, space-saving design, high pulse load capacity, rapid heat dissipation, and efficient SMD mounting.
