The 471KD07J-TB is a varistor through-hole component manufactured by Yageo. It is comprised of a ceramic disk coated with metal oxide and has symmetrical voltage-current characteristics. It is classified as a RoHS-compliant device and is designed to safely divert an electrical excess of the normal operating voltage away from sensitive circuits. It is designed to protect against electrical surges, impulses and transients. The device has a maximal energy rating of 5.0J and a highly linear dynamic impedance. It operates within a temperature range of -55°C to 85°C and is encased in an epoxy-filled package. Additionally, it demonstrates excellent noise and interference attenuation and has low junction capacitance for wideband operation.
