Chip resistors are a common component in electronic circuits, used to limit the flow of electric current. They come in a variety of models and specifications, each designed for specific applications. In this article, we will explore the differences between mainstream chip resistor models, including their construction, materials, and performance characteristics.
Thick film chip resistors are the most common type of chip resistors, known for their high stability and reliability. They are made by depositing a thick film of resistive material, typically a ceramic paste containing metal oxides, onto a ceramic substrate. The resistive material is then fired at high temperatures to form a solid film.
Thick film chip resistors are available in a wide range of resistance values, from a few ohms to several megaohms. They are also available in various power ratings, typically ranging from 1/16 watt to 2 watts. Thick film chip resistors are suitable for general-purpose applications, such as voltage dividers, current sensing, and pull-up or pull-down resistors.

Thin film chip resistors are made by depositing a thin film of resistive material, typically a metal alloy such as nickel-chromium or tantalum nitride, onto a ceramic substrate. The resistive material is then etched to achieve the desired resistance value. Thin film chip resistors are known for their high precision and stability, making them ideal for precision applications.
Thin film chip resistors are available in a narrower range of resistance values compared to thick film chip resistors, typically ranging from a few ohms to a few kiloohms. They are also available in higher power ratings, typically ranging from 1/16 watt to 1 watt. Thin film chip resistors are commonly used in precision voltage dividers, precision current sensing, and high-frequency applications.
