Chip Resistor
SMD resistor, also known as chip fixed resistor, is a type of metal glaze resistor.
It is made by mixing metal powder and glass glaze powder and printing it onto a substrate using screen printing.
It is resistant to moisture and high temperature, with a low temperature coefficient.
It greatly saves circuit space cost and enables more refined circuit design.
