SFI0806SV241-201A-UL

The SFI0806SV241-201A-UL is a specific part number of a surface mount varistor designed to protect electronic circuits from damage caused by voltage surges and transients. Similar to other varistors, it works by forming a voltage-dependent barrier and switching from a high to low resistance state when the voltage across it exceeds a certain threshold to protect connected devices.

The SFI0806SV241-201A-UL varistor has a maximum voltage rating of 10V and a rated current of 200mA, making it suitable for low voltage applications. It also has a tolerance rating of ±10% indicated by the "201A" in its part number, and a capacitance rating of 240pF, enabling it to protect against high voltage surges and transients.

The UL certification of the varistor indicates that it is of high quality, meets appropriate safety standards, and is free from hazardous substances such as lead and other environmental pollutants.

With its small size and surface mount form factor, the SFI0806SV241-201A-UL varistor is easy to integrate into various circuit designs. It is particularly useful in electronic devices that are vulnerable to damages caused by voltage surges such as power supplies, microcontrollers, and more.

In summary, the SFI0806SV241-201A-UL varistor is an effective electronic component that provides protection against voltage surges and transients in low voltage circuits by rapidly switching from high to low resistance when a voltage threshold is reached.
