Product Attributes

Introduction

This device is a resettable overcurrent protection component in a 1206 SMT package, based on Polymeric Positive Temperature Coefficient (PPTC) technology. It is connected in series in a circuit to provide overcurrent protection — when a fault current exceeds a specific threshold for a sufficient duration, its resistance increases sharply, thereby limiting the current. Once the fault is cleared, the device cools down and resets to a low-resistance state. Key features include resettability, fast trip time, low power consumption, RoHS compliance, and lead-free/halogen-free construction.
