Description and Introduction

Silicon temperature sensors The KTY81-210 is a silicon temperature sensor manufactured by PHILIPS (now NXP Semiconductors). Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:  

### **Specifications:**  
- **Temperature Range:** -55°C to +150°C  
- **Output:** Linear resistance change with temperature  
- **Resistance Values:**  
  - 1 kΩ at 25°C  
  - 2.1 kΩ at 150°C  
- **Tolerance:** ±1.5% at 25°C  
- **Temperature Coefficient:** Positive (resistance increases with temperature)  
- **Power Dissipation:** Typically 10 mW (max. 100 mW)  
- **Thermal Time Constant:** ~5 s in still air  

### **Descriptions:**  
- The KTY81-210 is a silicon-based temperature sensor with a linear resistance-temperature characteristic.  
- It is designed for precision temperature measurement in automotive, industrial, and consumer applications.  
- The sensor operates without external signal conditioning, making it simple to integrate into circuits.  

### **Features:**  
- High accuracy and linearity over a wide temperature range.  
- Stable and reliable performance with long-term stability.  
- Small size and robust construction for harsh environments.  
- Low self-heating effect due to low power dissipation.  
- Compatible with standard silicon processing techniques.  

This information is based on the manufacturer's datasheet and technical documentation.
