GQ0B031003CT Description

The GQ0B031003CT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 19-resistor array features a 100K Ohm resistance value with an ultra-tight 0.25% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70 to 125°C). Housed in a 20-pin QSOP ceramic package, it offers a 1W total power rating (0.05W per resistor) and supports 100V maximum voltage. Its gull-wing termination and surface-mount design facilitate reliable PCB integration, while the tube packaging ensures safe handling and storage.

GQ0B031003CT Features

• Precision Thin Film Technology: Delivers high accuracy (±0.25%) and low TCR (±25ppm/°C) for stable operation in thermal variations.
• Robust Ceramic Case: Enhances durability and heat dissipation, ideal for high-temperature environments (up to 125°C).
• Compact QSOP Package: Measures 8.66mm (L) × 6.02mm (D) × 1.47mm (H) with tight tolerances (±0.1mm height/length), saving board space.
• BUS Circuit Design: Optimized for bus termination, voltage division, and pull-up/down applications.
• High Voltage Rating: Supports up to 100V, suitable for industrial and instrumentation circuits.
• Non-Automotive Grade: Compliant with EAR99 (ECCN) but not PPAP or RoHS certified.
