DLA | Precision Current Sense Resistor

The Isabellenhütte 25004 / VMK is a DLA-qualified precision current sense resistor designed for high-reliability applications requiring controlled performance, traceability and long-term stability.
Manufactured in a compact 1206 surface-mount package, this two-terminal resistor provides accurate current measurement in space-constrained designs.

With resistance values ranging from 10mΩ to 470mΩ and a 0.75W power rating at 70 °C, the VMK supports stable and repeatable current sensing across a wide operating range.
The resistor is engineered for consistent electrical behaviour, with low drift and strong thermal performance, ensuring measurement accuracy under varying load and temperature conditions.

Designed for extreme environments, the device operates from −65°C to +170°C and is available in industrial (Test Code A), military (Test Code B) and space-level (Test Code T) variants.
These options meet stringent qualification and testing requirements, making the VMK suitable for mission-critical systems.
