Description and Introduction

UL 1434 1st Edition CSA C22.2 No. 0 CSA TIL No. CA-3A The SMD1210P050TS is a surface-mount PTC resettable fuse designed for overcurrent protection in electronic circuits. Below are its key specifications, descriptions, and features:  

### **Manufacturer:**  
- **Bourns** (Model: SMD1210P050TS)  

### **Specifications:**  
- **Rated Voltage:** 6V DC  
- **Hold Current (I_H):** 0.50A  
- **Trip Current (I_T):** 1.00A  
- **Max Current (I_MAX):** 40A  
- **Resistance (R_min):** 0.08Ω  
- **Resistance (R_max):** 0.40Ω  
- **Power Rating:** 1.5W  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** 1210 (3225 metric)  

### **Description:**  
- A **resettable PTC (Positive Temperature Coefficient) fuse** that provides overcurrent protection by increasing resistance when excessive current flows, then resets when the fault is removed.  
- Designed for **surface-mount (SMD) applications** in compact PCB designs.  

### **Features:**  
- **Resettable:** Automatically recovers after fault removal.  
- **Fast Response:** Quickly reacts to overcurrent conditions.  
- **RoHS Compliant:** Meets environmental standards.  
- **Compact Size:** Suitable for space-constrained designs.  
- **Reliable Protection:** Guards against short circuits and overcurrent events.  

This information is based on Bourns' datasheet for the SMD1210P050TS. For detailed performance curves or application notes, refer to the official manufacturer documentation.
