Product Description
SMD Moulded Power Resistor
TE Connectivity (TE) introduces the SM Series, a surface mount power resistor designed to meet modern circuit design requirements. These resistors feature a low-profile case with flexible tinned copper terminations for robust solder joints. Utilizing a fully welded construction, the SM Series can withstand high temperatures associated with reflow, vapor phase, or infrared (IR) manufacturing processes without degradation. They are ideal for power circuitry and are available in a wide value range and up to 7 Watts power rating.
