摘要： The present invention proposes a resistor with two barrier layers covered by a protection layer, at both sides of the resistor to resist the moisture and sulphide penetration from both sides. The barrier can enhance the anti-corrosion ability of the resister. For a metallic barrier, a distance to the resistance layer and the internal electrode layer is necessary.

摘要： Solution-processed negative temperature coefficient (NTC) thermistor devices include transition metal dichalcogenide (TMDC) quantum dots. The TMDC quantum dots may be formulated into an ink, and the ink may subsequently be deposited on a substrate and processed to form an NTC thermistor. Solution-processed NTC thermistors may be incorporated into RFID tags or as circuit protectors into electronic circuits.

摘要： 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.

摘要： A power resistor comprises a tubular housing composed of metal and a resistor element received therein, wherein the housing has four side walls that extend along a longitudinal axis of the housing between two ends and define a rectangular cross-section. The housing comprises four edges of the four side walls at at least one of the two ends. Two of the four side walls have a respective incision at their edges for introducing a fastening element and the two other side walls have a respective clearance in alignment with the oppositely disposed incision to facilitate a placement of a tool at a fastening element introduced into the respective incision.

摘要： The invention relates to an overvoltage protection device with varistors, wherein a first varistor and a second varistor are connected in series, wherein the first varistor has a thermal disconnector, wherein the first varistor has a lower operating voltage than the second varistor, and wherein the first varistor has a lower energy absorption capacity than the second varistor, with the first varistor heating up more in the event of an overload and thereby causing the thermal disconnector to disconnect.
