Description and Introduction

SMD Type, 6 V / 9 V / 15V The SMD0805P050TF is a PTC resettable fuse manufactured by Polytronics (聚鼎). Here are its specifications, descriptions, and features:

### **Specifications:**
- **Type:** PTC Resettable Fuse  
- **Package Size:** 0805 (2.0mm x 1.25mm)  
- **Hold Current (I_H):** 0.50A  
- **Trip Current (I_T):** 1.00A  
- **Voltage Rating:** 6V (DC)  
- **Max Voltage (Vmax):** 30V (DC)  
- **Max Current (Imax):** 40A  
- **Power Rating:** 0.1W (at 25°C)  
- **Resistance (Rmin/Rmax):** 0.1Ω / 0.5Ω  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**
- **Function:** Provides overcurrent protection by increasing resistance when excessive current flows, then resets when fault is removed.  
- **Applications:** Used in consumer electronics, power supplies, USB ports, and battery protection circuits.  

### **Features:**
- **Resettable:** Automatically recovers after fault condition.  
- **Compact Size:** Suitable for space-constrained PCB designs.  
- **Fast Response:** Quickly trips in overcurrent conditions.  
- **RoHS Compliant:** Meets environmental standards.

Application Scenarios & Design Considerations

SMD Type, 6 V / 9 V / 15V

Alternative Part Number

  • MF-MSMF050-2 --: Resettable PTC fuse in 0805 size with 0.5A hold current, matching the electrical and footprint requirements of the original.
  • 0ZCG0050AF2E --: 0805 surface-mount PPTC with 0.5A hold current and similar trip characteristics, suitable as a direct functional replacement.
  • LVR005S-2 --: PolySwitch resettable fuse with 0.5A hold current; verify footprint since it may be a slightly larger package, but electrically compatible.
  • PTS0805-050 --: 0805 resettable PTC fuse rated 0.5A hold current, similar trip characteristics and package.
