These characters are characterized by being designed to be connected horizontally and/or vertically with adjacent characters, which requires proper alignment.
Junction temperature, short for transistor junction temperature, [1] is the highest operating temperature of the actual semiconductor in an electronic device. In operation, it is higher than case temperature and the temperature of the part's exterior. The difference is equal to the amount of heat transferred from the junction to case multiplied by the junction-to-case thermal resistance.
How to Choose a Junction Box Sizes . The typical junction box size for residential use is a 4-inch square box, which is roomy enough for multiple wires and cables.
