Description and Introduction

Silicon temperature sensors The KTY81/121 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  
- **Accuracy:** ±0.5°C at 25°C  
- **Resistance Values:**  
  - 1 kΩ at 25°C  
  - 1.6 kΩ at 100°C  
- **Temperature Coefficient:** Positive (resistance increases with temperature)  
- **Operating Voltage:** Up to 30 V  
- **Current Consumption:** Typically 1 mA (depends on biasing conditions)  
- **Package:** SOT23 (Surface Mount)  

### **Descriptions:**  
- The KTY81/121 is a linear silicon temperature sensor with a positive temperature coefficient (PTC).  
- It is designed for precise temperature measurement in industrial, automotive, and consumer applications.  
- The sensor provides a resistance output that varies linearly with temperature, making it suitable for analog temperature monitoring.  

### **Features:**  
- **High Accuracy:** Low deviation (±0.5°C at 25°C) ensures reliable temperature readings.  
- **Wide Temperature Range:** Operates from -55°C to +150°C.  
- **Linear Response:** Resistance changes predictably with temperature, simplifying calibration.  
- **Robust Construction:** Suitable for harsh environments, including automotive applications.  
- **Low Power Consumption:** Operates efficiently with minimal power requirements.  
- **Small Form Factor:** SOT23 package enables compact PCB integration.  

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