Description and Introduction

SMD Type, 6 V - 60 V Here is the factual information about the part **SMD1812P014TFA** from the manufacturer **聚鼎 (Polytronics)**:

### **Specifications:**
- **Part Number:** SMD1812P014TFA  
- **Manufacturer:** 聚鼎 (Polytronics)  
- **Type:** Polymer Positive Temperature Coefficient (PPTC) Resettable Fuse  
- **Package:** 1812 (4532 Metric)  
- **Hold Current (I_H):** 1.4A  
- **Trip Current (I_T):** 2.8A  
- **Voltage Rating (Vmax):** 30V  
- **Max Current (Imax):** 40A  
- **Power Rating (Pmax):** 3.5W  
- **Operating Temperature Range:** -40°C to +85°C  
- **Resistance (Rmin/Rmax):** 0.03Ω / 0.30Ω  

### **Descriptions:**
- The **SMD1812P014TFA** is a surface-mount 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:** Automatically recovers after fault removal.  
- **Surface-Mount Design:** Suitable for PCB assembly.  
- **Fast Trip Response:** Provides quick protection against overcurrent.  
- **RoHS Compliant:** Meets environmental regulations.  
- **Reliable Performance:** Stable operation in various conditions.

Application Scenarios & Design Considerations

SMD Type, 6 V - 60 V

Alternative Part Number

  • MF-MSMF014-2 --: Same 1812-size PTC resettable fuse with 0.14A hold current and comparable voltage rating, widely available and a direct functional drop-in.
  • 0ZCG0014FF2B --: 1812 SMD PTC with 0.14A hold current and similar trip characteristics, suitable replacement for overcurrent protection.
  • RUEF140 --: Radial-lead PTC with 1.4A hold current family naming; check footprint, but offers similar resettable fuse function if layout allows leaded parts.
  • 0ZCG0014FF2E --: 1812 SMD PTC with 0.14A hold current and similar voltage rating, suitable drop-in replacement.
  • LVR014S --: Resettable PTC fuse with 0.14A hold current; verify package size as it may be radial rather than 1812 SMD.
  • 0ZCG0140AF2B --: 1812 SMD PTC with similar 140mA hold current and voltage rating, suitable drop-in replacement.
  • 1812L014DR --: 1812 polyfuse with 140mA hold current, comparable trip characteristics and footprint.
