GUS-QS0B-03-2490-FB Description

The GUS-QS0B-03-2490-FB from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 19-resistor array features a 249 Ohm resistance value per element with a tight 1% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature range of -70°C to +125°C. Housed in a compact 20-pin QSOP package with gull-wing terminations, it offers a power rating of 1W (0.05W per resistor) and a maximum voltage rating of 100V, making it suitable for high-density PCB designs. The rectangular package (8.66mm x 6.02mm x 1.47mm) with ±0.1mm length/height tolerances ensures reliable mounting consistency.

GUS-QS0B-03-2490-FB Features
