Product Description
Product Overview
The ISA-PLAN SMV-PW series from Isabellenhtte are high-precision resistors designed for demanding applications, including aerospace. These resistors offer 3 W permanent power 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.
