EXB-U18391JX

EXB-U18391JX Description

The EXB-U18391JX from Panasonic Electronic Components is a high-performance 4-resistor array designed for precision surface-mount applications. This 0502 (1406 Metric) convex, long-side terminal package offers a compact footprint of 0.055" × 0.024" (1.40mm × 0.60mm) with a low-profile height of 0.018" (0.45mm), making it ideal for space-constrained PCB designs. Each resistor in the array features a 390Ω resistance with a ±5% tolerance and a ±200ppm/°C temperature coefficient, ensuring stable performance across varying environmental conditions. The isolated circuit type allows for independent resistor operation, while the 31mW power rating per element ensures reliable power handling in low-power circuits.
