Description and Introduction

SMD Type, 6 V - 60 V The SMD1812P125TSA is a surface-mount PTC resettable fuse manufactured by Bourns. Here are its specifications, descriptions, and features:

### **Specifications:**  
- **Maximum Voltage (Vmax):** 30V DC  
- **Hold Current (Ihold):** 1.25A  
- **Trip Current (Itrip):** 2.5A  
- **Maximum Current (Imax):** 40A  
- **Power Rating:** 3.2W (at 20°C)  
- **Resistance (Rmin/Rmax):** 0.05Ω / 0.20Ω  
- **Operating Temperature Range:** -40°C to +85°C  

### **Description:**  
The SMD1812P125TSA is a polymer-based PTC (Positive Temperature Coefficient) resettable fuse designed for overcurrent protection in electronic circuits. It automatically resets once the fault condition is removed.  

### **Features:**  
- **Resettable:** Returns to low resistance after fault removal.  
- **Surface-Mount Design:** 1812 package size (4.6mm x 3.2mm).  
- **Fast Trip Response:** Provides quick protection against overcurrent.  
- **RoHS Compliant:** Meets environmental standards.  
- **Reliable Performance:** Suitable for automotive, industrial, and consumer electronics.  

This information is based solely on the manufacturer's datasheet.

Description and Introduction

SMD Type, 6 V - 60 V Here are the factual details about the part SMD1812P125TSA from the manufacturer 聚鼎 (Polytronics):  

### **Specifications:**  
- **Part Number:** SMD1812P125TSA  
- **Manufacturer:** 聚鼎 (Polytronics)  
- **Type:** Polymer Positive Temperature Coefficient (PPTC) Resettable Fuse  
- **Package Size:** 1812 (4.5mm x 3.2mm)  
- **Rated Voltage:** 12V  
- **Hold Current (Ihold):** 1.25A  
- **Trip Current (Itrip):** 2.5A (typical)  
- **Maximum Current (Imax):** 40A  
- **Power Rating:** 3.0W (at 20°C)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Resistance (Rmin/Rmax):** Typically 0.03Ω / 0.30Ω  

### **Descriptions:**  
- The SMD1812P125TSA is a surface-mountable resettable fuse designed for overcurrent protection in electronic circuits.  
- It operates based on PPTC technology, which increases resistance when excessive current flows, protecting the circuit.  
- After tripping, it resets automatically when the fault condition is removed and power is cycled.  

### **Features:**  
- **Resettable Function:** Automatically recovers after fault removal.  
- **Fast Trip Response:** Provides quick protection against overcurrent.  
- **Compact SMD Package:** Suitable for high-density PCB designs.  
- **RoHS Compliant:** Meets environmental standards.  
- **UL Recognized:** Certified for safety and reliability.  

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