resistor Isabellenhuette SMV-R330-1.0-PW suitable for IR wave soldering and high pulse power ratings
Product Overview
The ISA-PLAN SMV-PW series precision resistors, size 4723, from Isabellenhtte are designed for high-performance applications requiring excellent long-term stability and high pulse power ratings. These resistors offer 3 W permanent power at 80 C and continuous current load up to 30 A (at 3.3 mOhm). Suitable for aerospace and other demanding environments, they feature a wide applicable temperature range of -55 to +140 C and are compatible with reflow-, IR-, and wave-soldering processes. The SMV-PW series meets detail specification ESCC 4001/028 and is available with SnPb tinned contacts.
