Detailed Pin Configuration

The MINISMDC350LR-2 has two terminals for surface mount installation. The pin configuration is as follows: - Pin 1: Anode - Pin 2: Cathode

Functional Features

• Resettable: Automatically resets after the fault condition is removed
• Overcurrent Protection: Safeguards electronic circuits from excessive current flow
• Polymeric PTC: Utilizes polymeric materials with positive temperature coefficient for enhanced protection

Advantages and Disadvantages

Advantages

• Small form factor suitable for compact electronic designs

Disadvantages

• Limited hold current and trip current ratings compared to some traditional fuses
• Sensitive to ambient temperature variations

Working Principles

When an overcurrent event occurs, the MINISMDC350LR-2 heats up due to the increased current flow, causing its resistance to rise rapidly. This effectively limits the current passing through the device, protecting the circuit. Once the fault is removed, the device cools down and returns to its low-resistance state.

Detailed Application Field Plans

The MINISMDC350LR-2 is commonly used in various electronic applications, including: - Consumer Electronics - Automotive Electronics - Industrial Control Systems - Telecommunications Equipment - Power Supplies

Detailed and Complete Alternative Models

• MINISMDC260F/16-2: Similar PPTC device with lower hold and trip currents
• MINISMDC110F/24-2: PPTC device with higher voltage rating and lower hold current

In conclusion, the MINISMDC350LR-2 offers reliable overcurrent protection in a compact form factor, making it an essential component in modern electronic designs across various industries.
