GQCA0127R4JGT Description

The GQCA0127R4JGT 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 24-pin QSOP package integrates 12 isolated resistors, each rated at 27.4Ω ±5% tolerance, with a ±100ppm/°C temperature coefficient. The ceramic case ensures excellent thermal stability, while the gull-wing termination facilitates reliable surface-mount assembly. With a 1W total power rating (0.1W per resistor) and a maximum operating temperature of 125°C, this network is engineered for demanding environments. Its 100V maximum voltage rating and isolated circuit design (ISOL) make it suitable for applications requiring electrical separation between channels.

GQCA0127R4JGT Features

• Thin-Film Technology: Delivers superior accuracy, stability, and low noise compared to thick-film alternatives.
• High-Density Integration: 12 resistors in a compact 8.66mm × 6.02mm × 1.47mm QSOP package, optimizing PCB space.
• Robust Construction: Ceramic substrate enhances thermal dissipation and mechanical durability.
• Precision Performance: Tight tolerance (±5%) and low TCR (±100ppm/°C) ensure consistent operation across 70°C to 125°C.
• Automated Assembly-Friendly: Gull-wing leads and 0.64mm terminal pitch simplify pick-and-place processes.
• Non-Automotive (PPAP No): Ideal for industrial, telecom, and instrumentation applications where automotive compliance is not required.
