Description
technical field [0001] The invention relates to the technical field of heat dissipation resistors, in particular to a high-efficiency heat dissipation well-shaped high-power resistor. Background technique [0002] With the rapid development of industrialization, resistors are used more and more frequently. Resistors are generally called resistors in daily life. They are a current-limiting element. After the resistor is connected to the circuit, the resistance value of the resistor is fixed. Generally, there are two pins, which can limit the current through the branch connected to it. Those whose resistance value cannot be changed are called fixed resistors, and those whose resistance value is variable are called potentiometers or variable resistors. Ideal resistors It is linear, that is, the instantaneous current through the resistor is proportional to the applied instantaneous voltage, and is used for voltage dividing variable resistors. On the exposed resistor body, one o...
