A surge protection device includes a metal terminal and a spring. The metal terminal is located between two metal oxide varistors, where the metal terminal extends beyond the metal oxide varistors. The spring has a flat surface that is connected to the metal terminal using a soldering paste. The flat surface has a bend on one end which forms a gap between the flat surface and the metal terminal.

High soldering strength terminal for surge protection device

A flat spring () is disclosed, for use in a surge protection device (SPD) such as a fast activation thermal fuse, to be integrated with a thermal metal oxide varistor (TMOV). The flat spring () has a V-shaped protrusion () to enable ultra-high short circuit current protection under overvoltage condition.

Fast activation thermal fuse for short circuit current protection

Disclosed are various pallet assemblies for arc spray applications. In some embodiments, an assembly may include a top frame comprising a plurality of recesses each operable to receive an electronic device, and a bottom frame coupled to the top frame, wherein the bottom frame comprises a plurality of support structures, and wherein each support structure of the plurality of support structures is aligned with a corresponding recess of the plurality of recesses. The assembly may further include a mechanical device coupled to the top frame and the bottom frame, wherein the mechanical device is operable to bias the top frame and the bottom frame relative to one another.

Height-adjustable masking pallet assembly for arc spray applications

Provided herein are thermally protected varistor (TPV) devices including a varistor body and a terminal assembly directly coupled together. The terminal assembly may include a housing, wherein an opening is provided in a base of the housing. A lead is coupleable with the varistor body via a thermal linking material positioned within the opening of the base, the thermal linking material operable to maintain direct physical contact with the lead when the thermal linking material is below a melting point. The terminal assembly may further include a shield slidable within the housing between a first position and a second position, wherein in the first position the shield is positioned adjacent the thermal linking material, and in the second position the shield is positioned between the lead and the second side of the varistor body. The shield includes a tab for releasably coupling the shield to the housing.
