Product Overview
The ISA-PLAN SMV-PW series precision resistors, size 4723, are designed for demanding applications requiring high power and excellent stability. These resistors offer 3 W permanent power at 80 C and continuous current load up to 30 A (at 3.3 mOhm). They are characterized by their excellent long-term stability and high pulse power rating. Suitable for aerospace applications, these resistors meet the detail specification ESCC 4001/028 and feature SnPb tinned contacts. They are compatible with reflow-, IR-, and wave-soldering mounting methods.
