MF-R110-0-99

Product Overview

Category

The MF-R110-0-99 belongs to the category of resettable fuses, also known as PTC (positive temperature coefficient) thermistors.

Use

These resettable fuses are used to protect electrical circuits from overcurrent and short circuit conditions. They provide a self-recovery feature, making them suitable for applications where frequent power cycling may occur.

Characteristics

  • Resettable: The MF-R110-0-99 can return to its normal state after the fault condition is removed.
  • Current Limiting: It limits the amount of current that can flow through a circuit.
  • Compact Package: The fuse comes in a small and space-saving package, suitable for various electronic devices.
  • Essence: The essence of this product lies in its ability to protect sensitive electronic components from damage due to overcurrent events.

Packaging/Quantity

The MF-R110-0-99 is typically packaged in reels or trays, with quantities varying based on customer requirements.

Specifications

  • Hold Current: 1.1A
  • Trip Current: 2.2A
  • 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-R110-0-99 features two terminals for connection within a circuit. The pin configuration is as follows: - Pin 1: Connection terminal 1 - Pin 2: Connection terminal 2

Functional Features

  • Self-Recovery: After the fault condition is removed, the fuse resets itself, eliminating the need for manual replacement.
  • Overcurrent Protection: Provides protection against excessive current flow, safeguarding the circuit and connected components.
  • Fast Response: Quickly reacts to overcurrent events, minimizing the risk of damage to the circuit.

Advantages and Disadvantages

Advantages

  • Self-recovery feature reduces maintenance and replacement costs.
  • Compact size allows for integration into space-constrained designs.
  • Provides reliable overcurrent protection for sensitive electronics.

Disadvantages

  • Limited trip current range compared to traditional fuses.
  • May have a higher initial cost compared to non-resettable fuses.

Working Principles

The MF-R110-0-99 operates based on the principle of PTC thermistor behavior. When exposed to overcurrent conditions, the thermistor's resistance increases, limiting the current flow through the circuit. Once the fault is removed, the thermistor cools down and returns to its low-resistance state, allowing normal operation to resume.

Detailed Application Field Plans

The MF-R110-0-99 is commonly used in various electronic devices and systems, including: - Consumer electronics - Power supplies - Battery packs - Automotive electronics - Industrial control systems

Detailed and Complete Alternative Models

  • MF-R160-0-99
  • MF-R200-0-99
  • MF-R250-0-99
  • MF-R500-0-99

In summary, the MF-R110-0-99 resettable fuse offers compact, self-recovering overcurrent protection for a wide range of electronic applications, making it an essential component in modern circuit design.
