GQCB014420FCT Description

The GQCB014420FCT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 23-resistor array features a 442Ω resistance value with a tight 1% tolerance and a low ±100ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). Housed in a 24-pin QSOP ceramic package, it offers a 1W total power rating (0.05W per resistor) and a 100V maximum voltage rating, making it suitable for demanding circuits. The gull-wing termination and surface-mount design facilitate easy PCB integration, while its compact dimensions (8.66mm x 6.02mm x 1.47mm) save board space.

GQCB014420FCT Features

• Precision Thin Film Technology: Delivers high accuracy (±1%) and low TCR (±100ppm/°C) for stable operation in varying environments.
• Robust Ceramic Case: Enhances thermal management and durability, ideal for high-temperature applications up to 125°C.
• BUS Circuit Designator: Optimized for bus line termination, voltage division, and pull-up/pull-down networks.
• QSOP Package: Compact 24-pin gull-wing SMD design with 0.64mm pitch for high-density PCB layouts.
• Non-Automotive Grade: Suitable for industrial, telecom, and instrumentation use where PPAP compliance is not required.
