Negative temperature coefficient thermistor

Introduction to Negative Temperature Coefficient Thermistor

A negative temperature coefficient thermistor (NTC thermistor) is a type of temperature sensor that exhibits a decrease in resistance as temperature rises. These thermistors play a critical role in various applications across industries, including medical devices, automotive systems, and consumer electronics. Their unique properties allow for precise temperature measurement and control, making them invaluable in regulating electrical devices and ensuring efficient operation.

Types of Negative Temperature Coefficient Thermistors

NTC thermistors come in several forms, each suited for specific applications. Understanding the different types can help you choose the right thermistor for your needs.

• Bead Thermistors: These are small, bead-like thermistors typically encapsulated in glass, offering rapid response times and are widely used in air temperature measurement.
• Disc Thermistors: Disc thermistors are flat, circular devices often used in applications requiring surface mounting. They are excellent for applications such as HVAC systems.
• Cylindrical Thermistors: These thermistors are cylindrical in shape and are ideal for immersion in liquids or gases, providing accurate readings in diverse environments.
• SMD Thermistors: Surface mount devices designed for compact applications, these thermistors can fit into tighter spaces, making them ideal for modern electronic devices.
