Detailed Pin Configuration

The RXEF065S has a radial leaded package with two pins. Pin 1 is the input terminal, and pin 2 is the output terminal.

Functional Features

• Resettable: The device automatically resets when the fault condition is removed.
• Overcurrent Protection: Limits the current flow in the circuit to protect the components from damage.
• Polymeric PTC: Utilizes a polymeric material with positive temperature coefficient characteristics.

Advantages and Disadvantages

Advantages

• Resettable nature increases the longevity of the device.
• Provides reliable overcurrent protection.
• Small form factor for space-constrained applications.

Disadvantages

• Limited maximum voltage compared to some alternative models.
• Trip current may not be adjustable.

Working Principles

When the current flowing through the RXEF065S exceeds the trip current, the device heats up, causing its resistance to increase significantly. This limits the current flow, protecting the circuit from damage. Once the fault condition is removed, the device cools down and resets to its low-resistance state.

Detailed Application Field Plans

The RXEF065S is commonly used in various electronic circuits requiring overcurrent protection, such as power supplies, battery packs, and automotive electronics. Its small form factor and resettable nature make it suitable for applications where reliability and longevity are crucial.

Detailed and Complete Alternative Models

• RXEF110S: Higher hold and trip currents, suitable for applications with higher power requirements.
• RXEF035S: Lower hold and trip currents, ideal for low-power circuits.

In conclusion, the RXEF065S is a resettable PPTC device designed for overcurrent protection in electronic circuits. Its compact size, resettable nature, and reliable performance make it a popular choice for a wide range of applications.
