Precision Resistor Type SMV Spec Sheet R431-1/2 Dec 97 Remarks: - Standard resistance values according to E12 with the additional values of 2 and 5 - Minimum quantity of other values on request - Tolerance 1% for values from 3 mOhm - Tolerance 0.5% for values from 10 mOhm Resistor type SMV is the low ohmic version of type SMR in four-terminal execution. The temperature coefficient therefore is very low over the complete range; the resistance value is likewise independent on the quality of the solder connection. A high load capacity is achieved with the bulk copper connections in conjunction with a good heat - conducting substrate for the resistor element inside, as well as a temperature resistant epoxy resin housing. 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.
