Popular Models of Common Thermistors

I. Introduction

I. Introduction

A. Definition of Thermistors

Thermistors, or thermal resistors, are temperature-sensitive resistors that exhibit a significant change in resistance with changes in temperature. They are made from ceramic materials that have semiconductor properties, allowing them to be highly sensitive to temperature variations. This unique characteristic makes thermistors invaluable in a wide range of applications, from consumer electronics to industrial systems, where precise temperature measurement and control are crucial.

B. Purpose of the Outline

This blog post aims to provide an overview of popular thermistor models, focusing on their types, specifications, applications, and factors to consider when selecting the right thermistor for specific needs. Understanding the different types of thermistors and their applications is essential for engineers, designers, and hobbyists alike, as it can significantly impact the performance and reliability of temperature-sensitive systems.

II. Types of Thermistors

Thermistors are primarily categorized into two types based on their temperature-resistance characteristics: Negative Temperature Coefficient (NTC) thermistors and Positive Temperature Coefficient (PTC) thermistors.

A. Negative Temperature Coefficient (NTC) Thermistors

NTC thermistors are characterized by a decrease in resistance as the temperature increases. This property makes them ideal for applications requiring precise temperature measurements and control. Common applications include temperature sensing in HVAC systems, automotive temperature monitoring, and battery management systems.

B. Positive Temperature Coefficient (PTC) Thermistors

In contrast, PTC thermistors exhibit an increase in resistance with rising temperature. This behavior makes them suitable for overcurrent protection and self-regulating heating applications. PTC thermistors are commonly used in applications such as motor protection, circuit protection, and as resettable fuses.

A. Temperature Range

The temperature range of the thermistor should match the operating conditions of the application. Ensure that the thermistor can operate effectively within the required temperature limits.

B. Resistance Value

The resistance value at a specific temperature (usually 25°C) is critical for accurate temperature measurement. Choose a thermistor with a resistance value that aligns with the application's requirements.

C. Size and Form Factor

The physical size and form factor of the thermistor are essential, especially in space-constrained applications. Consider whether a surface mount or through-hole design is more suitable.

D. Response Time

The response time of the thermistor is crucial for applications requiring rapid temperature changes. Ensure that the selected thermistor can respond quickly to temperature fluctuations.
