RXEF160 Product Overview

Introduction

The RXEF160 is a resettable polymeric positive temperature coefficient (PPTC) device belonging to the category of electronic components. This entry provides an in-depth overview of the RXEF160, including its basic information, specifications, pin configuration, functional features, advantages and disadvantages, working principles, application field plans, and alternative models.

Basic Information Overview

• Category: Electronic Components
• Use: Overcurrent Protection
• Characteristics: Resettable, Polymeric Material, Positive Temperature Coefficient
• Package: Radial Leaded
• Essence: Provides overcurrent protection by increasing resistance when current exceeds a certain threshold
• Packaging/Quantity: Available in reels or bulk packaging, quantity varies based on supplier

Specifications

• Maximum Voltage: 60V
• Hold Current: 1.6A
• Trip Current: 3.2A
• Operating Temperature Range: -40°C to 85°C
• Resistance: <0.1Ω (Initial), >10Ω (Trip)

Detailed Pin Configuration

The RXEF160 has two radial leads for easy integration into circuit boards. The pin configuration is as follows: - Pin 1: Connected to one end of the PPTC device - Pin 2: Connected to the other end of the PPTC device

Functional Features

• Resettable: The RXEF160 returns to a low-resistance state after the fault condition is removed.
• Overcurrent Protection: When the current exceeds the trip current, the device self-heats and increases its resistance, limiting the current flow.

Advantages and Disadvantages

Advantages

• Resettable nature allows for multiple uses
• Provides reliable overcurrent protection
• Compact size for easy integration into circuits

Disadvantages

• Limited hold current compared to some alternatives
• Trip time may vary based on ambient temperature

Working Principles

The RXEF160 operates based on the positive temperature coefficient effect of the polymeric material. When the current exceeds the trip current, the device self-heats, causing the resistance to increase significantly, thereby limiting the current flow and providing overcurrent protection.

Detailed Application Field Plans

The RXEF160 is commonly used in various electronic applications, including: - Power Supplies - Battery Packs - Automotive Electronics - Consumer Electronics - Industrial Control Systems

Detailed and Complete Alternative Models

Several alternative models to the RXEF160 include: - RXEF110: Lower hold current, suitable for more sensitive applications - RXEF200: Higher hold current, suitable for higher power applications - RXEF250: Higher trip current, suitable for applications with larger current surges

In conclusion, the RXEF160 is a resettable PPTC device that offers reliable overcurrent protection in a compact package. Its working principle, application field plans, and alternative models provide a comprehensive understanding of its capabilities and usage scenarios.
