Detailed Pin Configuration

The RUEF300K-2 has two terminals for surface mount installation.

Functional Features

• Resettable: Automatically resets when the fault condition is removed.
• Overcurrent Protection: Safeguards against excessive current flow.
• Surface Mount Design: Suitable for compact electronic applications.

Advantages and Disadvantages

Advantages: - Resettable functionality increases product lifespan. - Small form factor suitable for space-constrained designs.

Disadvantages: - Limited hold and trip current ratings compared to some alternatives. - Sensitive to temperature variations.

Working Principles

The RUEF300K-2 operates based on the PPTC effect, where its resistance increases with temperature rise due to overcurrent conditions. Once the fault is removed, the device cools down and returns to a low-resistance state.

Detailed Application Field Plans

The RUEF300K-2 is commonly used in various electronic devices such as battery packs, power supplies, and consumer electronics to provide overcurrent protection in small form factor applications.

Detailed and Complete Alternative Models

• RUEF500K-2: Higher hold and trip current ratings for more demanding applications.
• RUEF100K-2: Lower hold and trip current ratings for less power-hungry designs.
