Abstract
A surface mount component (11) has at least one lead (12) which extends from a body portion (16) of the component (11) along an axis (14) through the component. An outer end portion of the lead (12) is formed into a circuit termination (20) of a shape which, when projected onto a plane perpendicular to the axis, encompasses a projection of the body portion (16) of the component onto the plane.
Claims13
An electrical surface mount component assembly, which comprises:
- a substrate having a flat mounting surface and having a circuit pattern formed on such mounting surface, said circuit pattern including spaced contact pads;
- at least one surface mount component including a body portion oriented longitudinally parallel and adjacent to said mounting surface of the substrate, said body portion housing the electrical component;
- at least a first and a second lead having an inner end portion attached to the body portion and extending from the body portion parallel to said mounting surface of the substrate in a direction toward said spaced contact pads;
- and
- a circuit termination formed form an outer end portion of each lead into a shape which encompasses a projection of the shape of the body portion in the direction toward the formed termination, the termination of each lead being mounted to a respective one of the spaced contact pads to retain the component longitudinally oriented adjacent to the mounting surface of the substrate.

An electrical component adapted to be surface mounted to a substrate having a flat mounting surface with spaced contact pads thereon, the component comprising:
- a body portion housing the component;
- first and second leads, each lead having an inner end portion attached to the body and an outer end portion, the inner end portions of the leads extending in opposite directions away from the body portion along an axis through the body portion and into respective planes perpendicular to said axis and spaced from the body portion;
- each lead having a circuit termination formed from the outer end portion thereof into a substantially closed shape lying substantially in its respective plane perpendicular to the axis and being larger in a diametral dimension than the body portion such that an imaginary projection of the body portion along the axis and onto the plane is encompassed by the termination;
- the terminations of both the first and second leads having substantially the same shape and diametral extent, such that when mounted to the spaced contact pads on the flat mounting surface said axis is substantially parallel to the flat mounting surface.
