Abstract
The present invention provides filters configured for use in surface mount technology (SMT). The high performance SMT filters of the present invention are formed of an exterior housing surrounding a smaller, similarly configured metal bracket. Electrically connected to the interior of the metal bracket are the filter internal components. Inside the metal bracket, and surrounding the filter internal components, is a solidified void-filling material such as epoxy. The ground leads of the filter are an integral part of the metal bracket giving excellent ground connection from the filter internal components to the surface mount circuit board. The high performance SMT filters of the present invention are especially adaptable to highly automated, high-throughput manufacturing techniques.
