Equivalent

The MF-SMDF050-2 is a polymeric positive temperature coefficient (PTC) resettable fuse. Equivalent products include the Littelfuse RHEF050 and Bourns MF-MSHT050. These components function similarly by providing overcurrent protection and resetting after the fault condition clears. Always verify specifications, such as hold current, trip current, and voltage rating, to ensure compatibility with your application.

Features

The MF-SMDF050-2 is a Polymeric Positive Temperature Coefficient (PPTC) resettable fuse designed for overcurrent protection. Here are its key features:
1. Current Rating: It typically has a hold current of 0.50A.
2. Voltage Rating: The operating voltage is usually around 60V DC.
3. Resistance: The device offers a low initial resistance.
4. Resettable: This fuse is resettable and returns to its normal condition after the fault is removed and power is cycled.
5. Compact Size: It is designed for surface mount technology (SMT), making it suitable for compact circuit boards.
6. Fast Response Time: Provides quick response to overcurrent conditions to protect circuits.
7. Durability: Designed to withstand multiple trip cycles.
8. Applications: Commonly used in telecommunications, industrial, and consumer electronics applications.
These features make the MF-SMDF050-2 an ideal choice for various electronic applications requiring reliable and resettable protection.

Pinout

The MF-SMDF050-2 is a polymeric positive temperature coefficient (PTC) resettable fuse, often referred to as a multifuse. It does not have traditional pins like an integrated circuit or connector would, as it is designed for surface mount technology (SMT). Instead, it has two terminals for electrical connection.
The primary function of the MF-SMDF050-2 is to provide overcurrent protection. Under normal operating conditions, the device has low resistance, allowing current to pass through. In the event of an overcurrent or a short circuit, the device heats up and its resistance increases significantly, effectively limiting the current flow to a safe level. Once the fault condition is removed and the device cools down, it resets and returns to its low-resistance state, ready for normal operation again. This resettable feature makes it particularly useful for applications requiring automatic recovery after fault conditions, such as in power supplies, battery packs, and consumer electronics.

Manufacturer

The MF-SMDF050-2 is a product manufactured by Bourns, Inc. Bourns is a global company known for its work in the electronics industry. It specializes in the design, manufacturing, and distribution of electronic components. These components are often used in various applications across telecommunications, automotive, consumer electronics, industrial automation, and other sectors. Bourns is recognized for its innovation in circuit protection, sensors, and controls solutions, among other products.

Application

The MF-SMDF050-2 is a PolySwitch resettable PTC (Positive Temperature Coefficient) device used in overcurrent protection applications. Its primary application areas include telecommunications, networking equipment, consumer electronics, and industrial controls. It is particularly useful in safeguarding USB ports, power adapters, and battery packs by limiting current flow during overcurrent conditions and automatically resetting once the fault is cleared. Its compact size and reliable performance make it a suitable choice for protecting circuits in various electronic devices.

Package

The MF-SMDF050-2 is a surface-mount device (SMD) package type, typically used for electronic components such as polymer PTC resettable fuses. It's designed for automated assembly processes and offers space-saving advantages on printed circuit boards (PCBs).
