Description and Introduction

Surface Mount PTC Devices The SMD2920P150TS is a PTC resettable fuse manufactured by 聚鼎 (Polytronics). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** 聚鼎 (Polytronics)  
- **Part Number:** SMD2920P150TS  
- **Type:** PTC Resettable Fuse  
- **Hold Current (Ihold):** 1.5A  
- **Trip Current (Itrip):** 3.0A  
- **Voltage Rating (Vmax):** 30V DC  
- **Resistance (Rmin/Rmax):** 0.05Ω / 0.30Ω  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** 2920 (7.4mm x 5.0mm)  

### **Descriptions:**
- The SMD2920P150TS is a surface-mount resettable fuse designed for overcurrent protection.  
- It operates as a positive temperature coefficient (PTC) thermistor, increasing resistance when excessive current flows, thereby limiting the current.  
- Automatically resets when the fault condition is removed and the device cools down.  

### **Features:**
- **Resettable:** Returns to a low-resistance state after fault removal.  
- **Surface-Mount Design:** Suitable for PCB applications.  
- **Fast Trip Response:** Protects circuits quickly under overcurrent conditions.  
- **High Voltage Rating:** Supports up to 30V DC.  
- **RoHS Compliant:** Meets environmental standards.  

This information is based solely on the manufacturer's provided data for the SMD2920P150TS.
