MINISMDC125F-2

Introduction

The MINISMDC125F-2 is a surface mount polymeric positive temperature coefficient (PPTC) device that belongs to the category of resettable fuses. This component is widely used for overcurrent protection in various electronic circuits due to its unique characteristics and functional features.

Basic Information Overview

  • Category: Resettable Fuse
  • Use: Overcurrent Protection
  • Characteristics: Polymeric Positive Temperature Coefficient, Surface Mount
  • Package: SMD (Surface Mount Device)
  • Essence: Provides overcurrent protection by limiting the current flow in the circuit
  • Packaging/Quantity: Typically available in reels or tape and reel packaging with varying quantities

Specifications

  • Voltage Rating: 60V
  • Hold Current: 1.25A
  • Trip Current: 2.5A
  • Operating Temperature Range: -40°C to 85°C
  • Maximum Time to Trip: 60 seconds at 200% of rated current

Detailed Pin Configuration

The MINISMDC125F-2 has a standard SMD pin configuration with two terminals for surface mounting onto the circuit board.

Functional Features

  • Resettable: Automatically resets when the fault condition is removed
  • Overcurrent Protection: Limits the current during overcurrent conditions
  • Compact Design: Suitable for space-constrained applications
  • Reliable Performance: Provides consistent protection over multiple fault cycles

Advantages and Disadvantages

Advantages

  • Resettable functionality increases the lifespan of the component
  • Compact size makes it suitable for miniaturized designs
