Conductive grounding from Chomerics provide EMI protection by establishing low impedance ground paths between electrically conductive elements in a chassis or component. These stabs forestall interference from the surface currents that “excite” metal components and thus create “phantom” fields. The tabs can be used to provide the required grounding paths economically as compared to reworking a design or installing enclosure shielding. For example, slot length in enclosure seams can be reduced effectively using conductive tabs at appropriate intervals. With wavelength the determining factor, the smaller slot size may limit leakage sufficiently to circumvent continuous gasketing. This will provide a cost savings. Within enclosures, grounding tabs may reduce radiated EMI levels from a PCB ground plane saturated with signals. Board-mounted component shields, such as metal cans, can be grounded with conductive tabs inserted between the shield and enclosure wall. Typical applications include information technology and wireless handset shielding and grounding. More product information can be found at the Chomerics’website.
