MF-R075-AP

Product Overview

Category

The MF-R075-AP 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-R075-AP can return to its normal state after the fault condition is removed.
  • Self-protecting: It does not require replacement after a fault condition, reducing maintenance costs.
  • Fast response time: Provides quick protection against overcurrent events.
  • Compact size: Suitable for use in space-constrained applications.

Package

The MF-R075-AP is typically available in tape and reel packaging for automated assembly processes.

Essence

The essence of the MF-R075-AP lies in its ability to provide reliable overcurrent protection while offering the convenience of a resettable device.

Packaging/Quantity

It is commonly packaged in reels with quantities varying based on customer requirements.

Specifications

  • Hold Current: 0.75A
  • Trip Current: 1.5A
  • Voltage Rating: 30V
  • Operating Temperature Range: -40°C to 85°C
  • Maximum Time-to-Trip: 60 seconds at 25°C

Detailed Pin Configuration

The MF-R075-AP features two terminals for connection within a circuit. The pin configuration is as follows: - Pin 1: Connection terminal - Pin 2: Connection terminal

Functional Features

  • Overcurrent Protection: Limits the current flow during overcurrent conditions to protect the circuit.
  • Resettable Operation: Returns to a low-resistance state once the fault is cleared.
  • Reliable Performance: Ensures consistent protection over multiple fault cycles.

Advantages and Disadvantages

Advantages

  • Resettable functionality reduces maintenance and replacement costs.
  • Fast response time provides effective protection against overcurrent events.
  • Compact size allows for versatile integration into various electronic devices.

Disadvantages

  • Limited hold current compared to some non-resettable fuse options.
  • Trip time may vary based on operating temperature and ambient conditions.

Working Principles

The MF-R075-AP operates based on the PTC effect, where its resistance increases significantly when subjected to overcurrent conditions. This increase in resistance limits the current flow, protecting the circuit. Once the fault is removed, the device cools down and returns to its low-resistance state.

Detailed Application Field Plans

The MF-R075-AP is widely used in various electronic applications, including: - Consumer electronics - Automotive electronics - Industrial control systems - Telecommunications equipment

Detailed and Complete Alternative Models

  • MF-R050-AP: Lower hold current variant for applications with lower current requirements.
  • MF-R110-AP: Higher hold current variant suitable for applications with higher current demands.
  • MF-R250-AP: Increased hold current and trip current for more robust protection.

In conclusion, the MF-R075-AP offers reliable overcurrent protection with the added benefit of resettable operation, making it a valuable component in modern electronic designs.
