NTC-T105K16

series introduction

# Introduction to the NTC - T105K16 Product Series

## 1. Overview
The NTC - T105K16 product series belongs to the category of Negative Temperature Coefficient (NTC) thermistors. These thermistors are essential components in a wide range of electronic and electrical systems, offering precise temperature - sensing capabilities. Their unique characteristic of having a negative temperature coefficient means that as the temperature increases, their electrical resistance decreases, and vice versa. This property makes them highly suitable for applications where accurate temperature measurement and control are crucial.

## 2. Key Specifications

### Resistance Value
The "105" in the NTC - T105K16 model indicates that at a reference temperature of 25°C (also known as the nominal temperature), the thermistor has a resistance value of 1 MΩ (since 10 × 10⁵ Ω = 1 MΩ). This specific resistance value at 25°C is carefully calibrated during the manufacturing process to ensure high accuracy in temperature - related applications.

### Tolerance
The "K" in the model number represents a tolerance of ±10%. This means that the actual resistance value of the thermistor at 25°C can vary within ±10% of the nominal 1 MΩ value. For example, the actual resistance at 25°C could range from 900 kΩ to 1.1 MΩ. While a ±10% tolerance might seem relatively large in some high - precision applications, it is still suitable for many general - purpose temperature - sensing tasks.

### B - Value
The B - value is a critical parameter for NTC thermistors as it describes the relationship between resistance and temperature. The "16" in the NTC - T105K16 indicates a specific B - value. The B - value is defined as the temperature coefficient of the resistance and is calculated using the formula:

\[B = \frac{\ln(\frac{R_1}{R_2})}{\frac{1}{T_1}-\frac{1}{T_2}}\]

where \(R_1\) and \(R_2\) are the resistances at absolute temperatures \(T_1\) and \(T_2\) respectively. A well - defined B - value ensures that the thermistor's resistance changes predictably with temperature, allowing for accurate temperature calculations in various applications.

## 3. Physical Characteristics

### Package Design
The NTC - T105K16 thermistors are typically available in a compact and robust package. The package is designed to protect the thermistor element from environmental factors such as moisture, dust, and mechanical stress. This ensures the long - term stability and reliability of the thermistor in different operating conditions.

### Size
The small size of the NTC - T105K16 makes it easy to integrate into various electronic circuits. Its compact form factor allows for high - density PCB (Printed Circuit Board) designs, which is particularly important in modern electronic devices where space is often limited.

## 4. Applications

### Temperature Measurement
One of the primary applications of the NTC - T105K16 series is temperature measurement. In industrial settings, it can be used to monitor the temperature of machinery, such as motors and transformers. By accurately measuring the temperature, potential overheating issues can be detected early, preventing equipment damage and downtime. In consumer electronics, it can be found in devices like laptops and smartphones to monitor the temperature of the CPU and battery, ensuring safe and efficient operation.

### Temperature Compensation
The NTC - T105K16 can also be used for temperature compensation in electronic circuits. Many electronic components, such as capacitors and resistors, have their electrical properties affected by temperature changes
