RUEF090S

Product Overview

Category

The RUEF090S belongs to the category of electronic components, specifically resettable fuses.

Use

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

Characteristics

• Resettable: Can return to its normal state 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 RUEF090S is typically available in surface mount packages.

Essence

The essence of RUEF090S lies in its ability to provide reliable overcurrent protection while being resettable for continued use.

Packaging/Quantity

It is commonly packaged in reels or trays, with quantities varying based on manufacturer specifications.

Specifications

• Maximum Voltage: 60V
• Hold Current: 0.9A
• Trip Current: 1.8A
• Operating Temperature Range: -40°C to 85°C

Detailed Pin Configuration

The RUEF090S has two pins for connection, typically labeled as "IN" and "OUT". The specific pin configuration can vary based on the manufacturer's datasheet.

Functional Features

• Overcurrent Protection: Automatically disconnects the circuit in case of overcurrent conditions.
• Resettable: Returns to normal operation once the fault is removed.
• Compact Size: Occupies minimal space on the PCB.

Advantages

• Reliable Overcurrent Protection
• Resettable Functionality
• Low Voltage Drop

Disadvantages

• Limited Maximum Voltage
• Sensitivity to High Ambient Temperatures

Working Principles

The RUEF090S operates based on the principle of positive temperature coefficient (PTC). When an overcurrent condition occurs, the resistance of the device increases, limiting the current flow and protecting the circuit. Once the fault is removed, the device cools down and returns to its low-resistance state.

Detailed Application Field Plans

The RUEF090S is commonly used in various electronic devices and systems, including: - Consumer Electronics - Automotive Electronics - Industrial Control Systems - Telecommunications Equipment

Detailed and Complete Alternative Models

• Bourns MF-R090
• Littelfuse 1812L090
• TE Connectivity POLY-FUSE RUEF090

In conclusion, the RUEF090S is a resettable fuse designed to provide reliable overcurrent protection in electronic circuits. Its compact size, resettable functionality, and fast response time make it suitable for a wide range of applications across different industries. However, users should be mindful of its maximum voltage limitations and sensitivity to high temperatures when considering its deployment. Additionally, alternative models such as the Bourns MF-R090, Littelfuse 1812L090, and TE Connectivity POLY-FUSE RUEF090 offer similar functionalities and can be considered based on specific application requirements.
