Abstract
A chip resistor includes a resistive element, a pair of electrodes, and heat radiator plates. The resistive element is made of a plate-shaped metal. The pair of electrodes is formed on both ends of a first surface of the resistive element. The heat radiator plates are fastened to a second surface of the resistive element and are disposed spaced apart from each other via a gap therebetween.
Claims8
A chip resistor comprising:
- a resistive element of a plate-shaped metal;
- first and second electrodes formed at both ends of a first surface of the resistive element;
- and
- a plurality of heat radiator plates fastened to a second surface of the resistive element,
