Product Description
ISA-PLAN Precision Resistors - TO 247 Size
The ISA-PLAN series offers high-performance precision resistors designed for demanding applications. These resistors feature high power ratings up to 10 W, constant current capabilities up to 70 A (for 2 mOhm), and a size similar to the TO 247 package. Key advantages include high pulse power handling, excellent long-term stability, 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
