RXEF135-AP

Product Overview

RXEF135-AP is a resettable fuse belonging to the category of electronic components. It is commonly used for overcurrent protection in various electronic circuits. The characteristics of RXEF135-AP include its compact size, high current-carrying capacity, and resettable functionality. The package includes the essence of a polymer PTC (Positive Temperature Coefficient) material, and it is available in tape and reel packaging with a specific quantity per reel.

Specifications

  • Voltage Rating: 60V
  • Current Rating: 1.35A
  • Hold Current: 1.35A
  • Trip Current: 2.7A
  • Max Voltage: 30V
  • Resistance: 0.04Ω

Detailed Pin Configuration

The RXEF135-AP has two pins for connection. Pin 1 is the input terminal, and pin 2 is the output terminal.

Functional Features

  • Resettable functionality
  • High current-carrying capacity
  • Fast response time

Advantages

  • Eliminates the need for replacement fuses
  • Provides reliable overcurrent protection
  • Compact size saves space in circuit design

Disadvantages

  • Limited maximum voltage rating
  • Trip current may cause nuisance tripping in some applications

Working Principles

The RXEF135-AP operates based on the PTC effect, where its resistance increases significantly when the current exceeds the trip current. This increase in resistance limits the current flow, providing overcurrent protection. Once the fault condition is removed, the device resets itself as it cools down, allowing normal operation to resume.

Detailed Application Field Plans

RXEF135-AP is widely used in various electronic devices and systems, including power supplies, battery packs, automotive electronics, and industrial control systems. Its resettable nature makes it suitable for applications where frequent overcurrent events may occur.

Detailed and Complete Alternative Models

  • RXEF110-AP: 1.1A current rating
  • RXEF160-AP: 1.6A current rating
  • RXEF200-AP: 2.0A current rating
  • RXEF250-AP: 2.5A current rating

In conclusion, RXEF135-AP is a versatile resettable fuse that provides reliable overcurrent protection in electronic circuits. Its compact size, high current-carrying capacity, and resettable functionality make it a preferred choice for various applications.
