An encircling graphene filter choke and a manufacturing method therefor. The choke comprises an inner coil part and an outer coil part. The inner coil part comprises a plurality of sets of first coils (10);the plurality of sets of first coils closely circles end to end in parallel to form a hollow tubular structure;an input end is leaded out from a first set of first coils;an inner coil connecting end is leaded out from the last set of first coils;the outer coil part comprises a plurality of sets of second coils (11);each set of second coils encircles the tubular structure from one end to the other end along the outer surface of the tubular structure, passes through the hollow inner surface, and returns to a starting end;the plurality of sets of second coils, end to end, closely encircles the tubular structure along the inner and outer surfaces;an outer coil connecting end is leaded out from a first set of second coils;an output end is leaded out from the last set of second coils;the inner coil connecting end and the outer coil connecting end are connected;a current to be filtered is input into the input end;and a filtered current is output from the output end.

An electrical power connector includes a power terminal having a first contact and a second contact arranged back-to-back. The first contact has a first thickness. The first contact has a first mating segment having a mating interface. The first contact has a first mounting segment including a first compliant pin. The second contact has a second thickness approximately equal to the first thickness. The second contact has a second mating segment having a mating interface. The second contact has a second mounting segment including a second compliant pin. The first compliant pin is aligned with the second compliant pin and arranged back-to-back such that both the first and second compliant pins are received in a common plated via of a circuit board.
