Stackpole has released two concave thick film chip resistor arrays. The RACF102D is a two-element array in a 0404 overall package size. The RACF104D is a four-element array in a 0408 overall package size. According to the company, both the chip resistor arrays ensure a significant space savings, improved tolerance and temperature coefficient of resistance tracking. The chip resistor arrays are available with a 5% tolerance, claims the company. They are suitable for pull up or pull down resistors, LED current limiting, memory modules, optics and optical instrumentation, communications and network equipment, multimedia, computer peripherals, and laser controls.
