GQCA0351R0JGT Description

The GQCA0351R0JGT 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 51Ω resistors with a 5% tolerance and a ±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 and electrical stability, making it suitable for surface-mount (SMD) applications. With a 1W total power rating (0.1W per resistor) and a 100V maximum voltage rating, this network is engineered for demanding circuits requiring isolation and durability.

GQQCA0351R0JGT Features

• Thin-Film Technology: Delivers superior accuracy, stability, and low noise compared to thick-film alternatives.
• Isolated Resistors (ISOL): Each of the 12 resistors operates independently, ideal for signal isolation or voltage division.
• High-Temperature Resilience: Operates reliably up to 125°C with derated power handling.
• Precision Tolerance: 5% resistance tolerance and ±25ppm/°C TCR ensure consistent performance in varying environments.
• Robust Construction: Ceramic substrate and gull-wing leads enhance thermal and mechanical reliability.
• Compact QSOP Package: 8.66mm × 6.02mm footprint with 1.47mm profile, optimized for space-constrained PCBs.
