EXB-28V121JX Description

The EXB-28V121JX from Panasonic Electronic Components is a high-performance 4-resistor array designed for precision surface-mount applications. This 120Ω isolated resistor network features a compact 0804 package (2.00mm x 1.00mm) with convex, long-side terminals, offering a low-profile height of 0.45mm—ideal for space-constrained designs. With a ±5% tolerance and ±200ppm/°C temperature coefficient, it ensures stable performance across varying environmental conditions. The device is RoHS3 compliant, REACH unaffected, and rated for 62.5mW power per element, making it suitable for demanding circuits. Packaged in Tape & Reel (TR), it supports automated assembly processes.
