The F-connector includes a connector body (220) with an extended center conductor lead (215). Attached to the F-connector and substantially surrounding the lead is an inductor, such as a toroid core (300) having windings (315) thereon. In one configuration one end (320) of the windings is attached to the center conductor lead and the other end (325) is attached to an electrical ground. In another configuration that other end is attached to a circuit ground via a capacitor, a power supply, or a biasing circuit. The inductor serves to shunt a surge to ground. A series capacitor is connected between the center conductor lead and an input/output port on an electronic circuit, passes the desired signal, and further helps to prevent a surge from reaching the device. ## Claims ### Claim 1 A connector with integrated surge protection, comprising: a conductive connector body having a front end and a back end;
