As little as 5 years ago, it would have been difficult to find a reliable 3-W SMT resistor, regardless of technology or packaging. Today, many different options are readily available. SMT molded packages are truly the future of the power electronics industry. Compliant terminations, the ability to withstand high temperatures, and the ability to accept many different types of resistive elements mean that this type of package should be at the top of the list for consideration by power design engineers. Whether their design is driven by electrical performance, environmental and long-term reliability, or cost, SMT molded resistors can provide the perfect solution.
