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