Technical Specifications

The SMD1210P005TF has a hold current (IHOLD) of 0.5A and a trip current (ITRIP) typically around 1A. It is designed for a maximum voltage rating (VMAX) of 16V. The device comes in a 1210 surface mount package. Its operating temperature range is from -40°C to +85°C. When an overcurrent condition occurs, the PPTC device heats up and its resistance increases significantly, limiting the current flow and protecting the circuit. Once the fault is removed and the device cools down, its resistance returns to a low value, allowing normal operation to resume. This resettable feature eliminates the need for manual replacement of fuses, enhancing convenience and reducing maintenance costs. The low resistance of the SMD1210P005TF ensures minimal voltage drop during normal operation, preserving the performance of the protected circuit. Its compact size and surface mount design make it easy to integrate into a variety of electronic devices. The SMD1210P005TF provides a reliable and cost-effective solution for overcurrent protection in electronic applications.
