RUEF500K

Product Overview

Use

It is used to protect circuits from overcurrent and short-circuit conditions.

Characteristics

Resettable: Can be automatically restored after a fault condition is removed.
Low resistance: Provides minimal voltage drop during normal operation.
Fast response time: Quickly reacts to overcurrent conditions to protect the circuit.

Package

The RUEF500K comes in a small, surface-mount package for easy integration into circuit boards.

Essence

The essence of RUEF500K lies in its ability to provide reliable overcurrent protection while allowing the circuit to resume normal operation after the fault is cleared.

Packaging/Quantity

It is typically packaged in reels containing a specific quantity, such as 3000 pieces per reel.

Specifications

Maximum Voltage: 60V
Hold Current: 5A
Trip Current: 10A
Operating Temperature Range: -40°C to 85°C

Detailed Pin Configuration

The detailed pin configuration of RUEF500K includes two terminals for connection to the circuit. The specific pinout can be found in the product datasheet.

Functional Features

Overcurrent Protection: Automatically trips in the event of an overcurrent condition, protecting the circuit.
Resettable: Once the fault is removed, the fuse resets itself, allowing the circuit to continue operating.

Advantages and Disadvantages

Advantages

Automatic reset capability reduces downtime.
Low resistance minimizes power loss in the protected circuit.

Disadvantages

Limited maximum voltage and current ratings compared to traditional fuses.
May not be suitable for high-power applications.

Working Principles

RUEF500K operates based on the principle of positive temperature coefficient (PTC). When an overcurrent condition occurs, the PTC material heats up, causing its resistance to increase and effectively limiting the current flow through the device.

Detailed Application Field Plans

RUEF500K is commonly used in various electronic devices and equipment, including: - Consumer electronics - Automotive electronics - Industrial control systems

Detailed and Complete Alternative Models

Some alternative models to RUEF500K include: - RUEF800K: Higher hold and trip currents for more demanding applications. - RUEF300K: Lower hold and trip currents for less power-hungry circuits.

In conclusion, RUEF500K is a resettable fuse designed to provide reliable overcurrent protection with the added benefit of automatic reset functionality. Its compact size and fast response make it suitable for a wide range of electronic applications.
