Detailed Pin Configuration

The RXEF010 has two radial leads for easy through-hole mounting on a PCB. The pin configuration is as follows: - Pin 1: Positive Lead - Pin 2: Negative Lead

Functional Features

• Resettable: Automatically resets when the fault condition is removed.
• Overcurrent Protection: Safeguards the circuit by limiting the current during overloads or short circuits.
• Polymeric Material: Provides durability and reliability in various environmental conditions.

Advantages and Disadvantages

Advantages

• Resettable nature increases product lifespan.
• Provides reliable overcurrent protection.
• Suitable for a wide range of operating temperatures.

Disadvantages

• Limited hold current and maximum voltage ratings compared to some non-resettable alternatives.
• Initial resistance may affect circuit performance in low-voltage applications.

Working Principles

When an overcurrent condition occurs, the RXEF010 heats up and undergoes a transition from a low-resistance state to a high-resistance state, effectively limiting the current flow. Once the fault is removed, the device cools down and returns to its low-resistance state, allowing normal operation to resume.

Detailed Application Field Plans

The RXEF010 is commonly used in various electronic devices and systems, including: - Power Supplies - Battery Packs - Automotive Electronics - Consumer Electronics - Industrial Control Systems

Detailed and Complete Alternative Models

• RXEF020: Higher hold current and maximum voltage ratings.
• RXEF005: Lower hold current and maximum voltage ratings, suitable for low-power applications.
• RXEF015: Intermediate hold current and maximum voltage ratings, balancing performance and space constraints.

In conclusion, the RXEF010 offers resettable overcurrent protection with the advantages of reliability and durability. Its limitations in terms of hold current and maximum voltage are balanced by its resettable nature and suitability for a wide range of applications.
