Chip fixed resistor, translated directly from chip fixed resistor, commonly known as chip resistor, is a type of metal glass glazed resistor. It is a resistor made by mixing metal powder and glass glaze powder and printing them on a substrate using screen printing method. Durable to moisture and high temperatures, with a small temperature coefficient, it can greatly save circuit space costs and make the design more refined.
The working temperature range of SDM resistors is -55~+125 ° C, and the maximum working voltage depends on the size: 0201 is the lowest, 0402 and 0603 are 50V, 0805 is 150V, and other sizes are 200V
