The RS45111ABA02 is an ALPS slide potentiometer with a 10 KOhms resistance rating, an accuracy of 20%, and a through-hole (THT) mounting design that uses a snap-in mount. It is primarily used for controlling the volume levels in audio equipment, and its 10 KOhms resistance makes it suitable for applications where a higher resistance value is desired. Its snap-in mounting design allows for easy installation and removal, making it suitable for portable audio equipment.
