A surface mount device, comprising: a first electrode comprising a chip carrier part; a second electrode disposed proximate to the chip carrier part and separated from the chip carrier part by an insulation gap; and a casing encasing a portion of the first electrode and a portion of the second electrode, and the casing having a recess extending from a first surface of the casing into the casing such that at least a portion of the chip carrier part is exposed through the recess; wherein the first electrode extends from the chip carrier part toward a perimeter of the casing, divides into a first plurality of leads (320, 325) separated by an aperture as the first electrode extends from the chip carrier part toward the perimeter of the casing; and the second electrode extends away from the chip carrier part, attains a second width prior to projecting outside of the casing, and projects outside of the casing maintaining the second width outside of the casing, and characterised in that the first plurality of leads join into a single first joined lead portion having a first width before the first electrode projects outside of the casing, and projects outside the casing maintaining the first width outside of the casing, and said chip carrier part widens to form first and second extension portions (335,340), wherein said first and second extension portions between said chip carrier part and said perimeter of the casing taper towards a central axis of said first electrode, wherein said first and second electrodes extend out opposing surfaces (140, 145) of the casing, wherein said second electrode comprises first and second lead portions (322, 327), which prior to exiting the casing at a fourth surface join into a single joined lead portion, and which include first and second head ends (337, 342), respectively, proximate said chip carrier part such that an edge of each of said head ends is parallel to an edge of said chip carrier part, and a portion of said chip carrier part extends between said head ends as the head ends taper away from the first electrode and toward the central axis. a first electrode comprising a chip carrier part; a second electrode disposed proximate to the chip carrier part and separated from the chip carrier part by an insulation gap; and a casing encasing a portion of the first electrode and a portion of the second electrode, and the casing having a recess extending from a first surface of the casing into the casing such that at least a portion of the chip carrier part is exposed through the recess; wherein the first electrode extends from the chip carrier part toward a perimeter of the casing, divides into a first plurality of leads (320, 325) separated by an aperture as the first electrode extends from the chip carrier part toward the perimeter of the casing; and the second electrode extends away from the chip carrier part, attains a second width prior to projecting outside of the casing, and projects outside of the casing maintaining the second width outside of the casing, and characterised in that the first plurality of leads join into a single first joined lead portion having a first width before the first electrode projects outside of the casing, and projects outside the casing maintaining the first width outside of the casing, and said chip carrier part widens to form first and second extension portions (335,340), wherein said first and second extension portions between said chip carrier part and said perimeter of the casing taper towards a central axis of said first electrode, wherein said first and second electrodes extend out opposing surfaces (140, 145) of the casing, wherein said second electrode comprises first and second lead portions (322, 327), which prior to exiting the casing at a fourth surface join into a single joined lead portion, and which include first and second head ends (337, 342), respectively, proximate said chip carrier part such that an edge of each of said head ends is parallel to an edge of said chip carrier part, and a portion of said chip carrier part extends between said head ends as the head ends taper away from the first electrode and toward the central axis.
