Product Overview
The ISA-PLAN SMV-PW series precision resistors, size 4723, are designed for demanding applications, including aerospace. These resistors offer a high continuous power rating of 3 W at 80 C and can handle continuous current loads up to 30 A (at 3.3 mOhm). They are characterized by excellent long-term stability, high pulse power rating, and are suitable for reflow, IR, and wave soldering processes. The SMV-PW series meets the detail specification ESCC 4001/028 and features SnPb tinned contacts.
