GQCA034302GT

GQCA034302GT Description

The GQCA034302GT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and low thermal drift. This 24-pin QSOP package integrates 12 isolated resistors, each rated at 43KΩ with a tight 2% tolerance and ±25ppm/°C temperature coefficient, ensuring reliable performance across a wide temperature range (70°C to 125°C). The ceramic case and gull-wing termination provide robust mechanical stability and ease of surface-mount assembly, while the 0.1W (1/10) power rating per resistor and 100V maximum voltage rating make it suitable for demanding circuits. Packaged in a tube, this non-automotive, non-PPAP compliant component is ideal for prototyping and low-to-medium volume production.

GQCA034302GT Features

• Precision Thin Film Technology: Delivers low noise and high stability for sensitive analog/digital circuits.
• Isolated Resistor Network (ISOL): 12 independent resistors minimize crosstalk in multi-channel systems.
• Wide Operating Range: -70°C to +125°C with derated power, ensuring reliability in harsh environments.
• Compact QSOP Package: 8.66mm × 6.02mm × 1.47mm dimensions with ±0.1mm length/height tolerances for space-constrained PCBs.
• Low TCR (±25ppm/°C): Critical for precision voltage dividers, feedback networks, and sensor interfaces.
• Gull-Wing SMT Termination: Facilitates automated assembly and inspection processes.

GQCA034302GT Applications
