Product Description
Product Overview
The ISA-PLAN series offers high-precision resistors designed for demanding applications. These resistors, with a size similar to the TO 247 package, provide high power handling capabilities up to 10 W and constant currents up to 70 A (for 2 mOhm). They are characterized by excellent long-term stability, low inductance, and high pulse power rating, 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 compliance since 01.01.2005
