MF-R135-0-99

Product Overview

Category

The MF-R135-0-99 belongs to the category of resettable fuses, also known as PTC (positive temperature coefficient) thermistors.

Use

It is used to protect electronic circuits from overcurrent and short-circuit conditions by limiting the flow of current in the event of a fault.

Characteristics

• Resettable: The MF-R135-0-99 can return to its normal state after the fault condition is removed.
• Package: It is available in a compact surface mount package.
• Essence: The essence of this product lies in its ability to provide reliable overcurrent protection in various electronic applications.
• Packaging/Quantity: Typically packaged in reels or trays, with quantities varying based on manufacturer specifications.

Specifications

• Hold Current: 1.35A
• Trip Current: 2.7A
• Maximum Voltage: 30V
• Operating Temperature Range: -40°C to 85°C
• Dimensions: 3.2mm x 1.6mm x 0.9mm

Detailed Pin Configuration

The MF-R135-0-99 features two terminals for connection within the circuit. The pin configuration is as follows: - Pin 1: Input/Anode - Pin 2: Output/Cathode

Functional Features

• Overcurrent Protection: Automatically limits the current flow when an overcurrent condition is detected.
• Resettable Operation: Returns to a low-resistance state once the fault is cleared.
• Compact Design: Suitable for space-constrained applications.

Advantages and Disadvantages

Advantages

• Resettable functionality increases product lifespan.
• Provides reliable protection against overcurrent events.
• Compact size allows for versatile integration into various circuit designs.

Disadvantages

• Limited maximum voltage compared to some non-resettable fuse alternatives.
• May have a slightly slower response time compared to traditional fuses.

Working Principles

The MF-R135-0-99 operates based on the principle of PTC thermistor behavior. When the current exceeds the hold current, the device heats up, causing its resistance to increase significantly, thereby limiting the current flow through the circuit. Once the fault is removed, the device cools down and returns to its low-resistance state.

Detailed Application Field Plans

The MF-R135-0-99 is commonly used in various electronic applications, including: - Power supplies - Battery packs - USB ports - Automotive electronics - Industrial control systems

Detailed and Complete Alternative Models

• MF-R005-0-99
• MF-R010-0-99
• MF-R020-0-99
• MF-R030-0-99
• MF-R050-0-99

In summary, the MF-R135-0-99 resettable fuse offers reliable overcurrent protection in a compact form factor, making it suitable for a wide range of electronic applications.
