RACF648NJT100R

RACF648NJT100R Description

The RACF648NJT100R from Stackpole Electronics, Inc. is an 8-resistor bussed network array designed for high-density surface-mount applications. Housed in a compact 2512 (6432 Metric) concave long-side terminal package, it offers a 100Ω resistance per element with a ±5% tolerance and ±200ppm/°C temperature coefficient. With dimensions of 0.252" x 0.122" (6.40mm x 3.10mm) and a low-profile height of 0.028" (0.70mm), this obsolete but still relevant component is ideal for space-constrained designs. The 62.5mW power rating per resistor ensures reliable performance in low-power circuits. Compliant with ROHS3 and REACH standards, it is packaged in Tape & Reel (TR) for automated assembly efficiency.
