Abstract: A reflowable thermal fuse includes a positive-temperature-coefficient (PTC) device that defines a first end and a second end, a conduction element that defines a first end and a second end in electrical communication with the second end of the PTC device, and a restraining element that defines a first end in electrical communication with the first end of the PTC device and a second end, in electrical communication with a second end of the conduction element. The restraining element is adapted to prevent the conduction element from coming out of electrical communication with the PTC device in an installation state of the thermal fuse. During a fault condition, heat applied to the thermal fuse diverts current flowing between the first end of the PTC device and the second end of the conduction element to the restraining element, causing the restraining element to release the conduction element and activate the fuse.

Abstract: A circuit protection device is configured to protect circuit elements under any one of the following three activation conditions: an over current condition, an over temperature condition, and an activation control current received by a heater element. The circuit element includes first and second electrodes, and the heater element. A sliding contact is connected by a sensing element to the first electrode, second electrode, and heater element, thereby bridging and providing a conductive path between each. A spring element is held in tension by, and exerts a force against, the sliding contact. Upon detection of any one of three activation conditions, the sensing element releases the sliding contact and the force exerted by the spring element moves the sliding contact to another location on the substrate at which the sliding contact no longer provides a conductive path between the first electrode, second electrode, and heater element.

Abstract: A circuit protection device includes a substrate with first and second electrodes connected to the circuit to be protected. The circuit protection device also includes a heater element between the first and second electrodes. A sliding contact is connected by a sensing element to the first electrode, second electrode, and heater element, thereby bridging and providing a conductive path between each. A spring element is held in tension by, and exerts a force parallel to a length of the substrate against, the sliding contact. A flux material is provided around the sensing element. Upon detection of an activation condition, the sensing element releases the sliding contact and the force exerted by the spring element moves the sliding contact to another location on the substrate at which the sliding contact no longer provides a conductive path between the first electrode, second electrode, and heater element. The flux allows the sliding contact to move without dragging the sensing material.

Abstract: A method for producing a surface mount device includes providing a plurality of layers including a B-staged top layer and bottom layer, and a C-staged middle layer with an opening. A core device is inserted into the openings, and then the top and bottom layers are placed over and under, respectively, the middle layer. The layers are cured until the layers become C-staged. The core device is substantially surrounded by an oxygen-barrier material with an oxygen permeability of less than approximately 0.4 cm3·mm/m2·atm·day.

Abstract: A reflowable thermal fuse includes a conduction element with first and second ends, disposed within a housing. The reflowable thermal fuse also includes an elastic element disposed within the housing and adapted to apply force on the conduction element in an activated state of the reflowable thermal fuse. A restraining element is utilized to secure the elastic element and prevent the elastic element from applying force on the conduction element in an installation state of the reflowable thermal fuse. Application of an activating current through the restraining element causes the restraining element to break and thereby release the elastic element and place the reflowable thermal fuse in the activated state.

Abstract: A thermal fuse includes a first contact surface connected to a top surface of a sensor and a bottom surface connected to a bottom surface of the sensor. The sensor includes a mixture of Sn and Zn. The distance between the top surface and the bottom surface of the sensor is sized to substantially limit Zn depletion in a center region of the sensor when a temperature of the sensor is below a melting temperature of the sensor. The center region of the sensor prevents the first contact surface and the second contact surface from separating when the temperature of the sensor is below the melting temperature, and the first contact surface and the second contact surface are configured to separate when the temperature of the center region of the sensor exceeds the melting temperature of the sensor.

Abstract: A circuit protection device includes a substrate with first and second electrodes connected to the circuit to be protected. The circuit protection device also includes a heater element. A sensing element facilitates an electrical connection between the first and second electrodes. A flux material is provided around the sensing element. In a preferred embodiment, the flux contains a first component that is a polar material and a second component that is a non-polar material. A spring element exerts a force on the sensing element. The sensing element resists the force applied by the spring element. Upon detection of an activation, or fault, condition, the sensing element loses resilience and no longer resists the force exerted by the spring element, resulting in the spring element severing the electrical connection between the first and second electrodes. The flux allows the spring element to sever with electrical connection without dragging the sensing element.
