Product Description
ISA-PLAN - Precision Resistors
The ISA-PLAN series offers high-performance precision resistors designed for demanding applications. These resistors feature a compact size similar to the TO 247 package, delivering up to 10W of power and constant currents up to 70A for the 2 mOhm variant. 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.
Product Attributes
- Brand: ISA-PLAN
- Size: Similar to TO 247
- Certifications: RoHS 2002/95/EC compliant since 01.01.2005
