II. Understanding Chip Resistors
A. What are Chip Resistors?
Chip resistors are small, rectangular components used to resist the flow of electric current in electronic circuits. They are typically made from a combination of conductive materials and substrates, which determine their performance characteristics. The construction of chip resistors allows them to be mounted directly onto circuit boards, making them ideal for compact electronic devices.
1. Description and Construction
Chip resistors are usually constructed from a resistive film deposited on a ceramic substrate. The resistive film can be made from various materials, including carbon, metal, or metal oxide. The size and shape of chip resistors can vary, but they are generally measured in millimeters, with common sizes being 0201, 0402, and 0603.
2. Types of Chip Resistors
There are several types of chip resistors, each with unique characteristics:
Thick Film Resistors: These are the most common type, made by screen printing a resistive paste onto a substrate. They are cost-effective and suitable for a wide range of applications.
Thin Film Resistors: These resistors are made by depositing a thin layer of resistive material onto a substrate. They offer higher precision and stability but are generally more expensive than thick film resistors.
Wirewound Resistors: These consist of a wire wound around a ceramic core. They are known for their high power ratings and precision but are bulkier than other types.
