Detailed Pin Configuration

The RXEF160K is a radial leaded PTC resettable fuse with two leads. The pin configuration is as follows: - Pin 1: Anode - Pin 2: Cathode

Functional Features

• Fast-acting response to overcurrent conditions
• Resettable functionality for repeated protection
• Surface mount design for easy integration into circuit boards

Advantages and Disadvantages

Advantages: - Fast response time - Resettable for multiple uses - Compact surface mount package

Disadvantages: - Limited maximum current rating - Sensitive to ambient temperature variations

Working Principles

The RXEF160K operates based on the principle of positive temperature coefficient (PTC) resistance. When an overcurrent condition occurs, the device heats up and its resistance increases, limiting the current flow through the circuit. Once the fault is removed, the device cools down and returns to its low-resistance state.

Detailed Application Field Plans

The RXEF160K is commonly used in various electronic devices and systems, including: - Power supplies - Battery packs - LED lighting - Consumer electronics

Detailed and Complete Alternative Models

• RXEF110K: 1.1A rated current
• RXEF250K: 2.5A rated current
• RXEF500K: 5.0A rated current

In conclusion, the RXEF160K is a fast-acting, resettable PTC fuse designed for overcurrent protection in electronic circuits. Its compact size and surface mount package make it suitable for a wide range of applications, although users should be mindful of its current rating limitations and sensitivity to temperature changes.
