The EMI fingers on my RJ connector project must have have tabs on on sides of the connector.Are these tabs needed on all sides to reduce the EMI issues.
 

From Jeffrey Tsai - As Xmultiple's Engineering Manager I would like to give you a complete answer with some background information.

(Xmultiple does recommend EMI fingers for reduction of EMI for most product designs. Please call us so we can discuss your specific design regarding this requirement.)
