GQCA033741CBT Description

The GQCA033741CBT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding applications requiring tight tolerances and stable performance. This 24-pin QSOP (Quarter Small Outline Package) device features 12 isolated resistors, each with a resistance value of 3.74KΩ and an exceptional tolerance of ±0.25%. The ceramic case ensures superior thermal stability, while the thin-film technology delivers low noise and high reliability. With a power rating of 1W (0.1W per resistor) and a temperature coefficient of ±25ppm/°C, this network is engineered for precision analog and digital circuits.

GQCA033741CBT Features

• High Precision: ±0.25% tolerance and ±25ppm/°C TCR ensure minimal drift in critical applications.
• Robust Construction: Ceramic case and gull-wing termination provide mechanical durability and excellent solderability.
• Isolated Design: 12 independent resistors (ISOL circuit designator) prevent crosstalk in multi-channel systems.
• Wide Operating Range: Rated for -55°C to +125°C, with derated power up to 125°C.
• Surface-Mount Ready: QSOP package (8.66mm × 6.02mm × 1.47mm) with 0.64mm pitch for compact PCB layouts.
• High Voltage Handling: Supports up to 100V, making it suitable for industrial and instrumentation use.
