The SMD1210-005-60V is a resettable fuse, also known as a Polymer Positive Temperature Coefficient (PPTC) thermistor, manufactured by TECHFUSE. It is designed to protect electronic circuits from overcurrent faults. When an overcurrent condition occurs, the 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, it returns to its low resistance state.

Applications

• USB ports
• Rechargeable batteries
• Power supplies
• Motor protection
• General electronic circuits

Features

• Resettable overcurrent protection.
• Surface mount device (SMD) package.
• Compact 1210 footprint.
• 60V maximum voltage rating.
• Fast trip time.

Benefits

• Provides reliable overcurrent protection without the need for manual replacement.
• Easy integration into circuit boards with SMD package.
• Small size saves board space.
• Suitable for a wide range of applications with 60V rating.
• Quick response to overcurrent faults protects sensitive components.

Additional Details

The SMD1210-005-60V has specific holding current and trip current ratings. Detailed specifications, including the holding current (Ihold), trip current (Itrip), and typical resistance values, are available in the TECHFUSE datasheet for this part number. The device's trip time depends on the magnitude of the overcurrent. This resettable fuse provides a cost-effective and reliable solution for overcurrent protection in various electronic devices.

The device is typically chosen based on the normal operating current of the circuit being protected. It's crucial to ensure the holding current exceeds the normal operating current to prevent nuisance tripping.
