    摘要： A reflowable thermal fuse including a fuse body, a conductive composite element disposed within the fuse body, first and second conductive terminals connected to the conductive composite element and extending out of the fuse body, a removable barrier covering a surface of the conductive composite element and in electrical communication with the first and second conductive terminals, and a solvent element disposed on the removable barrier and separated from the conductive composite element by the removable barrier, wherein the removable barrier has a fusing temperature that is greater than a reflow temperature of the reflowable thermal fuse

    摘要： A housing structure of a planar resistor is provided, wherein electrode extraction ends (4) of the planar resistor are on the same side of the resistor. A housing structure body (1) is made of an insulating material covering the surface of the resistor. An insulating structure (3) having a groove opening facing toward or away from the resistor is provided around each electrode extraction end (4) of the resistor. The insulating structure (3) is configured to be a multi-tooth or multi-groove insulating structure. Compared with the prior art, a structure having teeth or slots increases the surface creepage distance of an insulating material between two electrodes. Since the electrodes are mounted toward different directions, and a multi-groove opening is designed to face inward or outward, dust and dirt can hardly enter the resistor, so that the operating reliability and maintenance-free property of the resistor are improved.
