High reliability Isabellenhuette SMV-R033-1.0-PW resistor with 3 watt power rating and SnPb tinned contacts
Product Overview
The ISA-PLAN SMV-PW series precision resistors, size 4723, are designed for high-reliability applications, including aerospace. These resistors offer 3 W permanent power at 80 C and continuous current load up to 30 A (at 3.3 mOhm). Key features include excellent long-term stability, high pulse power rating, and suitability for reflow-, IR-, and wave-soldering. They meet the detail specification ESCC 4001/028 and feature SnPb tinned contacts.
