SMD Moulded Power Resistor Type SM Series Type SM Series Characteristics Electrical Tyco Electronics CGS introduces a surface mount power resistor suited to meet today's circuit design needs. Each size offers low profile case design with flexible tinned copper terminations for reliable solder joints. All styles utilize a fully welded SM (Wire) ---R10 - 200R R10 - 300R R10 - 500R Values SMF1: Values SM_2: Values SM_3: Values SM_5: Value Grid: Resistance Tolerance: Power Rating @ 25C SMF1: Power Rating @ 25C SM_2: Power Rating @ 25C SM_3: Power Rating @ 25C SM_5: Derating: Max Operating Voltage SMF1: Max Operating Voltage SM_2: Max Operating Voltage SM_3: Max Operating Voltage SM_5: SM (Metal Film) 10R - 2M 201R - 2M 301R - 2M 501R - 2M E24 1% or 5% ---- 1.0 Watt 2.0 Watts 3.0 Watts 5.0 Watts See Curve Below ---- 300 Volts 300 Volts 500 Volts 500 Volts construction technique, unlike other designs that rely solely on tinned termination connections. These features allow the SM Series to withstand the higher temperatures associated with reflow, vapour phase, or infrared (IR) manufacturing processes without degradation.
