The NVS0603H650ATR4KF varistor, manufactured by NIC Components, is a crucial component for protecting electronic circuits from voltage surges. This surface mount (SMD) varistor, available from Supreme Components International, an authorised distributor, offers a clamping voltage of 6.5V and a surge current rating of 2A. Its compact 0603 package makes it suitable for high-density PCB layouts. Varistors are voltage-dependent resistors that exhibit a significant decrease in resistance when a certain voltage threshold is reached, diverting excess current away from sensitive components. This particular model is designed to protect against electrostatic discharge (ESD) and other transient voltage events. The NVS0603H650ATR4KF is commonly used in applications such as mobile phones, tablets, and other portable devices where space is limited and reliable overvoltage protection is essential. Supreme Components International ensures the authenticity and quality of all NIC Components products.
