Introduction and Classification of SMT Chip Resistors (Part 1)

1. The concept of chip resistors

Chip resistors are also called chip resistors and surface mount resistors. Like other chip components, chip resistors are a new generation of leadless or short-leaded miniature electronic components suitable for surface mount technology (SMT). The welding surfaces of the leading ends are on the same plane. The main function of chip resistors in the circuit is to reduce the voltage, share a part of the voltage, that is, voltage division, current limiting protection circuit, shunt, etc., and can also be used as time circuit components and sensors.

2. Characteristics of chip resistors

Surface-mounted resistors are one of the components of surface-mounted vitality parts. They are passive components and are mainly used for thick film and thin film circuits as external components. It is generally classified in two ways. Classified according to characteristics and materials: thick film resistors, thin film resistors and thermistors. According to the shape and structure classification, it is divided into rectangular chip resistors, cylindrical chip resistors, and special-shaped resistors.
