Abstract

A circuit protection device includes a fuse placed in electrical communication with first and second conductors. An overvoltage protection component is placed in electrical communication with the first conductor and a third conductor. An insulative housing encloses the fuse, overvoltage protection component and portions of the first, second and third conductors. The first and second conductors include first and second terminal portions, respectively, that extend through the housing and reside at least substantially flush with an outer surface of the housing.

Description

technical field

[0001] The present invention generally relates to circuit protection components, and in particular to leadless integrated circuit protection components. Background technique

[0002] Certain electrical and electronic circuits require overcurrent and overvoltage protection. In the past, overcurrent and overvoltage protection has been achieved by at least two discrete components. Each element provides protection for a specific application. For example, discrete overcurrent elements are used to provide protection in the event of overcurrent. In addition, a discrete voltage suppressor is used to provide protection in case of excessive voltage. The two discrete components are interconnected by printed circuit board traces. Valuable space on the printed circuit board is consumed by the individual pin packaging of each component. Board designers are constantly looking for ways to save board space. Reducing the overall board space required for overcurrent and o...
