  • Trip Current: 2.7A
  • Maximum Current: 40A
  • Operating Temperature: -40°C to 85°C
  • Resistance: <0.1Ω

Detailed Pin Configuration

The MF-R135-AP has a standard SMD package with two terminals. The pin configuration is as follows: - Pin 1: Input/Anode - Pin 2: Output/Cathode

Functional Features

  • Resettable: Automatically resets after the fault condition is removed
  • Overcurrent Protection: Safeguards electronic circuits from excessive current flow
  • Compact Design: Space-efficient for integration into various electronic devices

Advantages and Disadvantages

Advantages

  • Resettable functionality increases reliability

Working Principles

The MF-R135-AP operates based on the principle of positive temperature coefficient (PTC) thermistors. When an overcurrent condition occurs, the device heats up, causing its resistance to increase significantly, thereby limiting the current flow. Once the fault is removed, the device cools down and returns to its low-resistance state, ready for normal operation.

Detailed Application Field Plans

The MF-R135-AP is widely used in various electronic applications, including but not limited to: - Consumer Electronics: TVs, Set-top Boxes, Home Appliances - Automotive Electronics: Control Units, Infotainment Systems - Industrial Equipment: Power Supplies, Motor Drives - Telecommunications: Network Devices, Routers, Switches

Detailed and Complete Alternative Models

Several alternative models to the MF-R135-AP include: - MF-R005-AP: Lower hold current for sensitive electronics - MF-R250-AP: Higher maximum current for industrial applications - MF-R500-AP: Ultra-high current rating for heavy-duty equipment

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