Introduction

RXEF017S is a resettable polymeric positive temperature coefficient (PPTC) device belonging to the category of electronic components. This entry provides an overview of 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, Positive Temperature Coefficient
• Package: Radial Leaded
• Essence: Provides overcurrent protection by increasing resistance in response to excessive current flow
• Packaging/Quantity: Available in reels with varying quantities

Specifications

• Hold Current: 0.17A
• Trip Current: 0.34A
• Maximum Voltage: 60V
• Operating Temperature Range: -40°C to 85°C
• Resistance: <1Ω in initial state, >10Ω in tripped state

Detailed Pin Configuration

The RXEF017S device has two radial leads for connection. 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: Returns to low-resistance state after the fault condition is removed
• Overcurrent Protection: Responds to excessive current by increasing resistance
• Reliable: Provides consistent protection against overcurrent events
• Compact Design: Suitable for space-constrained applications

Advantages and Disadvantages

Advantages

• Resettable nature allows for repeated use
• Provides effective overcurrent protection
• Compact size for versatile integration

Disadvantages

• Limited hold current capacity compared to some alternatives
• Trip current may be too high for certain low-power applications

Working Principles

When the current flowing through the RXEF017S exceeds the hold current, the device heats up and its resistance increases, limiting the current flow. Once the fault condition is removed, the device cools down and returns to its low-resistance state.

Detailed Application Field Plans

The RXEF017S is commonly used in various electronic circuits and systems requiring overcurrent protection, including: - Power Supplies - Battery Management Systems - Automotive Electronics - Consumer Electronics

Detailed and Complete Alternative Models

Some alternative models to RXEF017S include: - RXEF010: Lower hold current variant - RXEF020: Higher hold current variant - RXEF025: Higher voltage variant

In conclusion, RXEF017S offers reliable overcurrent protection in a compact and resettable package, making it suitable for a wide range of electronic applications.
