GQCB0145R3GFT Description

The GQCB0145R3GFT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 23-resistor array features a 45.3Ω resistance per element with a tight 2% tolerance and a low ±100ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of 70°C to 125°C. Housed in a 24-pin QSOP ceramic package, it offers a compact 8.66mm × 6.02mm footprint with gull-wing SMD termination for reliable surface mounting. The 1W total power rating (0.05W per resistor) and 100V maximum voltage rating make it suitable for demanding circuits. Its non-automotive, non-PPAP status and non-RoHS compliance may limit certain applications but ensure compatibility with legacy systems.
