PTC Resettable fuses are widely used across multiple types of electrical applications. The SMD1210P020TFA is a resettable fuse specifically designed for use in low-current applications. It is constructed from a polymeric positive temperature coefficient (PPTC) material that can be reset when necessary.

The SMD1210P020TFA is available in different sizes, with a minimum size of 0201. This allows the SMD1210P020TFA to fit into various applications where space is limited, such as automotive, industrial, and consumer electronics. The SMD1210P020TFA is also designed with an element that heats up when activated, allowing it to detect and respond to an overcurrent event. The device resets automatically when the fault is removed, providing an additional layer of safety for the application.

The SMD1210P020TFA has a wide application field due to its wide operating temperature range of -55°C to 85°C and high interrupting rating of up to 20A (100A surge). This makes the device suitable for use in automotive, consumer electronics, industrial, and other high-current applications. Additionally, the device is compliant with UL results, allowing for easy integration with other safety-focused devices.

The working principle of the SMD1210P020TFA is based on a polymeric positive temperature coefficient, or PPTC. This type of temperature-sensitive material has a low resistance when in an inactive state. When the current through the PPTC reaches a predetermined level, the material’s resistance will increase sharply, limiting the current. Once the fault is removed, the PPTC material cools and returns to its initial low-resistance state, allowing normal operation to be restored.

In summary, the SMD1210P020TFA is a powerful resettable fuse designed for low-current applications. Featuring a wide operating temperature range, UL compliant results, and a high interrupting rating, the device is suitable for use in automotive, consumer electronics, industrial, and other high-current applications. The device uses a PPTC element that can detect and limit an overcurrent event, resetting automatically when the fault is removed.
