KOA Thick Film Chip Resistors Get Expanded Range
Tiny chip resistors.
Bradford, PA — KOA Speer Electronics has expanded the range of resistance values of its smallest size within the RK73B1F series of general-purpose thick film chip resistors. The new value range, which affects the 01005 (1F) size, has been expanded to 4.70Ω to 1MΩ for both 2 percent and 5 percent tolerances.

The RK73B1F chip resistor, which is 55 percent smaller than the 0201 size, has a power rating of 0.03W and a TCR up to +300ppm/°C. All E-24 Values will be available for this resistor. In addition, this resistor is available with lead-free terminations to meet EU RoHS requirements.

Used primarily on portable products where size and/or weight are key factors, RK73B chip surface mount resistors are suitable for applications such as package-on-package (PoP) high density PCBAs, mobile phone RF modules, micro drives, handheld memory products (SD cards), portable application-mobile phones and digital cameras. The new chip resistor series is available in a wide range of sizes, from the 01005 (1F) up to 2512 (3WA). These chip resistors have a power rating range of 0.03W to 1W, resistances up to 22MΩ and maximum working voltages between 15V and 200V.
