Product Overview

The 1812L150-16DR is a surface-mount resettable overcurrent protection device (POLY-FUSE® PTC) designed for electronic equipment requiring efficient overcurrent protection. With a 1.50A hold current and 2.80A trip current, it quickly responds to overloads by limiting current and automatically resets after faults, eliminating the need for frequent replacement like traditional fuses. Ideal for space-constrained, high-precision circuit protection scenarios.

Key Features

• Rapid Response & Auto-Reset: Instantly increases resistance during overloads and resets without manual intervention, enabling maintenance-free continuous protection.
• Compact & Low Resistance: Uses an 1812 package (4.5mm×3.2mm) for high-density PCB layouts, with a typical internal resistance of 0.04Ω to minimize energy loss during normal operation.
• Wide Voltage Range & High Reliability: Supports 16V DC voltage and withstands up to 100A fault current, suitable for diverse complex circuit environments.
• High-Temperature Tolerance & Eco-Compliance: Compatible with 260°C reflow soldering, lead-free, halogen-free, and RoHS compliant for green manufacturing requirements.
• Precise Thermal Compensation: Built-in temperature-sensitive material adjusts protection thresholds according to ambient temperature, ensuring reliable protection under varying conditions.

Technical Specifications

Typical Applications

• Consumer Electronics: Protects USB interfaces and battery charging circuits in smartphones and tablets from overcurrent-induced damage or battery overheating.
• Computer Equipment: Safeguards motherboard, PCI cards, and peripheral interfaces (USB, HDMI) against transient overcurrent interference during high-speed data transmission.
• Industrial Control: Provides continuous overcurrent protection for sensor and driver circuits, adapting to harsh environments with vibration and temperature fluctuations.
• Communication Devices: Ensures stability and reliability of router/switch ports and power modules, enhancing system performance.

Why Choose 1812L150-16DR？

• Maintenance-Free Protection: Resettable design eliminates fuse replacement costs and time, improving equipment maintenance efficiency.
• Space-Optimized Solution: Miniature surface-mount package saves board space, perfect for portable devices and high-density integration.
• Low Power & High Stability: Low resistance reduces normal-state power consumption, with stable trip thresholds to avoid false triggers for long-term reliability.
• Harsh Environment Adaptability: Wide temperature range and high-temperature soldering tolerance meet complex application needs in industrial and consumer products.
• Global Compliance Assurance: RoHS compliance and international certifications support global production and supply chains, minimizing environmental and safety risks.
