RK73B Chip Resistors

KOA Speer RK73B Chip Resistors are available in a wide range of sizes, from the 01005 (1F) up to 2512 (3WA). These chip resistors feature a power rating range of .03W to 1W, resistances up to 22MΩ, and maximum working voltages between 15V and 200V. KOA Speer RK73B are ideal for applications such as package-on-package (PoP) high density PCBAs, mobile phones RF modules, micro drives, handheld memory products (SD cards), portable application-mobile phones, and digital cameras.
