GQCA021212GT

GQCA021212GT Description

The GQCA021212GT 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 12-resistor array features a 12.1KΩ resistance per element with a tight 2% tolerance and a low ±50ppm/°C temperature coefficient, ensuring reliable operation across a wide temperature range of 70°C to 125°C. Housed in a 24-pin QSOP ceramic package, it offers excellent thermal dissipation and mechanical durability, making it suitable for demanding environments. The isolated (ISOL) circuit design allows for individual resistor addressing, while the gull-wing termination ensures secure surface-mount attachment. With a 1W total power rating (0.1W per resistor) and a 100V maximum voltage rating, this component is ideal for precision analog and digital circuits.

GQCA021212GT Features

• High Precision: 12.1KΩ ±2% tolerance and ±50ppm/°C TCR for stable performance.
• Robust Construction: Ceramic QSOP case ensures thermal stability and mechanical strength.
• Isolated Design: 12 individually addressable resistors (ISOL configuration) for flexible circuit integration.
• Surface-Mount Ready: Gull-wing termination with 0.64mm pitch for reliable PCB mounting.
• Wide Operating Range: Rated for -55°C to +125°C, derated to 70°C at full power.
• Low Noise: Thin-film technology minimizes parasitic effects, critical for signal integrity.
• Compact Footprint: 8.66mm × 6.02mm × 1.47mm dimensions optimize board space.
