Abstract

An apparatus for protecting the conductor leads of an axial lead device includes a conductive shield having one or more openings configured to receive a plurality of conductor leads exiting from the axial lead device. The conductive shield may be structured and arranged to substantially surround a plurality of conductor leads received in the openings such that each conductor lead is isolated from at least one other conductor lead. The conductive shield may shunt radio frequency signals radiated by one or more of the plurality of conductor leads to a ground plane and isolate solder fillets and signal traces associated with the conductor leads when the axial lead device is surface mounted to a printed circuit board. Relative to an axial lead device when surface mounted to a PCB without the conductive shield, an assembly including an axial lead device and the conductive shield demonstrates other isolation of radio frequency signals across contacts of the assembly, higher isolation of radio signals across poles of the assembly, lower return loss of radio frequency signals, lower insertion loss of radio frequency signals, lower propagation delay time, and/or shorter pulse rise time.
