GQ0A021151GT Description

The GQ0A021151GT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and low temperature coefficients. This 10-resistor network features a 1.15KΩ resistance per element with a tight 2% tolerance and a ±50ppm/°C temperature coefficient, ensuring reliable performance across a broad operating temperature range of -70°C to +125°C. Housed in a 20-pin QSOP ceramic package, it offers excellent thermal stability and durability, making it suitable for demanding environments. The isolated (ISOL) circuit designator ensures individual resistor isolation, while the gull-wing termination facilitates easy surface-mount (SMD) assembly.

GQ0A021151GT Features

• Precision Thin Film Technology: Delivers high accuracy (±2%) and low TCR (±50ppm/°C) for stable performance.
• Robust Ceramic Package: Enhances thermal dissipation and mechanical strength, ideal for harsh conditions.
• High Power Handling: 1W total power rating (0.1W per resistor) with derating up to 125°C.
• Isolated Resistors (ISOL): Independent resistors minimize crosstalk in multi-channel circuits.
• Compact QSOP-20 Form Factor: Space-saving 8.66mm × 6.02mm × 1.47mm dimensions with ±0.1mm length/height tolerances.
• Wide Voltage Rating: Supports up to 100V, suitable for industrial and instrumentation applications.

GQ0A021151GT Applications

This resistor network excels in:

• Precision Analog Circuits: Voltage dividers, feedback networks, and sensor conditioning in test/measurement equipment.
• Industrial Control Systems: PLCs, motor drives, and power supplies requiring stable resistance under thermal stress.
• Medical Electronics: Isolated signal paths in patient monitoring devices.
• Automotive (Non-Automotive Compliant): Engine control units (ECUs) and infotainment systems (where PPAP/AEC-Q200 is not mandated).
