GQ0A012490GGT Description

The GQ0A012490GGT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and robust thermal performance. This 10-resistor network features a 249Ω resistance per element with a tight 2% tolerance and a low ±100ppm/°C temperature coefficient, ensuring reliable operation across a wide temperature range of 70°C to 125°C. Housed in a 20-pin QSOP ceramic package, it offers excellent thermal dissipation and mechanical durability, making it suitable for demanding environments. The gull-wing termination and surface-mount design facilitate easy PCB integration, while the 100V maximum voltage rating and 1W total power dissipation (0.1W per resistor) enhance its versatility in circuit designs.

GQ0A012490GGT Features

• Precision Thin Film Technology: Delivers stable resistance with minimal drift over temperature and time.
• High-Density Packaging: Compact 8.66mm × 6.02mm × 1.47mm footprint with 20 gull-wing terminals for space-constrained designs.
• Robust Construction: Ceramic case ensures superior thermal management and mechanical strength.
• Isolated Resistors: Independent circuit designator (ISOL) allows flexible routing and reduced crosstalk.
• Wide Operating Range: Supports -55°C to +125°C with derated power up to 125°C.
• Industry-Standard Compliance: Meets QSOP package standards with ±0.1mm length/height tolerances for consistent manufacturing.
