Chip resistor brief
SMD fixed resistors, directly translated from chip fixed resistor, commonly known as SMD resistors (SMD resistor), is a metal glass uranium resistor. It is a resistor made of metal powder and glass uranium powder, which is printed on the substrate by screen printing method. Resistance to humidity, high temperature, low temperature coefficient. (Note: The following chip fixed resistors are called chip resistors)
