Product Description
ISA-PLAN - Precision Resistors
The ISA-PLAN series offers high-power precision resistors designed for demanding applications. These resistors feature a TO 247-like package, providing high continuous current capabilities up to 70 A (for 2 mOhm) and a power rating of up to 10 W when mounted on a heatsink. Key advantages include excellent long-term stability, high pulse power handling, and low inductance, making them ideal for power modules, frequency converters, and switch-mode power supplies.
