Resistor type SMV is the low ohmic version of type SMR A high load capacity is achieved with the bulk copper

in four-terminal execution. The temperature coefficient connections in conjunction with a good heat - conducting

connection.

The resistor is also well suitable for switched applications

based on its low inductance.

The type SMV is delivered on a 24 mm belt in accordance

with EIA-481 for automated assembly.
